Question

The equations of two lines are y = -x - 6 and 2x - 3y = -2. What is the value of the y in the solution for this system of linear equations?

Answer 1

x = - 4

Explanation:

y = -x - 6

2x - 3y = -2

Insert the first equation y = -x-6 into the second 2x - 3y = -2 .

2x - 3 (-x-6) = -2

2x +3x + 18 = -2

5x = -2 - 18

5x = - 20

x = - 20/5

x = - 4
