How do you solve 7x - 2y = -8 and x = -2?

1 Answer

y=3

Explanation:

Since you were given the value of x which is 2, all you have to do is substitute this value to the given equation.

Solution:

7x2y=8
where x=2

substituting x value in the equation would give us:

7(2)2y=8
(14)2y=8

simplifying equation by transposing 14 to the right side,

2y=8+14
2y=6

Divide each side by 2 to get the value of y,

y=62

y=3
