plug in x value with given value

-7(-9)+8y=39

63+8y=39

move the 63

8y=39-63

subtraction

8y=-24

division

y=-3

Complete the solution of the equation. Find the value of y when x equals -9.

-7x + 8y = 39

The value of y is -3

-7x + 8y = 39

Substituting x = -9 in the equation,

=> -7(-9) + 8y = 39

=> 63 + 8y = 39

=> 8y = 39-63

=> 8y = -24

=> y = -24/8

=> y = -3

combine all like terms then its just a 2 step equation
