Answer is x = -7
Step by step
2x - 7y = -14
Solve for x by setting y at (0)
2x -7 (0) = -14
2x -0 = -14
2x = -14
Divide both sides by 2 to solve
2/2 x = -14/2
x = -7
To solve for y, set x at 0
2x - 7y = -14
2 (0) -7y = -14
0 -7y = -14
-7y = -14
Divide both sides by -7 to solve
-7/-7y = -14/-7
y = 2
