x = 2(x+2) + 3(x-1) = 3x + 7
2x + 4 + 3x -3 = 3x + 7
2x + 3x - 3x = 7 - 4 + 3
2x = 6
x = 3
Firstly, let's convert 10x + 2y = -2 to slope-intercept form (y = mx + b):
10x + 2y = -2
2y = -10x - 2
y = -5x - 2/5
The slope is -5. Parallel lines have the same slope; the question provides the y-int (12), so our equation is:
y = -5x + 12
Hope this helps.
