2y=-14+7x
-3x+2y=-6
First, express both equations in the form:
ax+by = c
-7x+2y=-14 (a)
-3x+2y=-6 (b)
Subtract (b)to (a)
-7x+2y=-14
-
-3x+2y=-6
____________
-4x = -8
Divide both sides by -4:
-4x/-4 = -8/-4
x = 2
Replace x on any equation and solve for y:
(b)
-3x+2y=-6
-3(2)+2y=-6
-6+2y= -6
Add 6 to both sides of the equation:
-6+6+2y= -6+6
2y=0
y=0
Solution:
x=2
y=0
