Question

8x + 5y = -3 and 6x + 25y = 2 solve simultaneous equation

Answer 1

Answer:

8x + 5y = -3 and 6x + 25y = 2 solve simultaneous equation

Answer 2

Step-by-step explanation:

By using substitution method

X = -3 - 5y / 8 --- equation 1

put the value of X = -3 - 5y / 8 in eqn 2

6x + 25y = 2

6 * -3 - 5y / 8 + 25 y = 2

-9 - 15y / 4 + 25y = 2

-9 - 15y +100y = 2*4

85y = 17

y = 1/5

put the value of y = 1/5 in eqn 1

X= -3 - 5y / 8

X = -1/2
