Question

3a +5b=26; a + 5b=22 please answer my question​

Answer 1

Answer:

3a+5b=26;a+5b=22

mark both of the equation as first and second respectively

now multiply second equation by 3

we get 3a+15b=66 now solve both the equations by elimination method

3a+5b=26

3a+15b=66

-10b=-40

b=4 now put the value of b in equation first

3a+5(4)=26

3a+20=26

3a=6

a=6

thanks.......,

Answer 2

Answer:

hence a=2,b=4

Step-by-step explanation:

3a+5b=26 ____equation 1

a+5b=22_______equation 2

- - -

_________

2a =4

__________

a=4÷2

a=2

put a=2 in equation 2

2 impulse 2+5b=22

5b=22-2

5b=20

b=20÷5

b=4
