Hey mate here's your answer if it helps plz plz mark me as brainliest answers.

The cost of one mooncake with two egg yolks is 12.80.

12.80.Step-by-step explanation:Let the cost of the mooncake with two egg yokes be “x” and that of the mooncake with 1 egg yolk be “y”.

“y”. It is given that the mooncake with two egg yolks costs 2 more than the mooncake with one egg yolk, therefore the eq. is,

more than the mooncake with one egg yolk, therefore the eq. is,x = 2 + y

more than the mooncake with one egg yolk, therefore the eq. is,x = 2 + y⇒ x – y = 2 ……. (i)Also given, the cost of 6 mooncakes with two egg yolks and 5 mooncakes with one egg yolk is 230.8, therefore the eq. is,

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.8

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12- + -

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12- + ------------------------

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12- + ------------------------ 11y = 118.8

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12- + ------------------------ 11y = 118.8------------------------

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12- + ------------------------ 11y = 118.8------------------------∴ y = 118.8/11 = 10.8

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12- + ------------------------ 11y = 118.8------------------------∴ y = 118.8/11 = 10.8Substituting y = 10.8 in eq. (i), we get

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12- + ------------------------ 11y = 118.8------------------------∴ y = 118.8/11 = 10.8Substituting y = 10.8 in eq. (i), we getx – y = 2

30.8, therefore the eq. is,6x + 5y = 130.8 ……. (ii)Now,Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get6x + 5y = 130.86x – 6y = 12- + ------------------------ 11y = 118.8------------------------∴ y = 118.8/11 = 10.8Substituting y = 10.8 in eq. (i), we getx – y = 2⇒ x = 2 + 10.8 = 12.8

12.8Thus, the cost of a mooncake with two egg yolks is 12.8.
