-1-2x-4x=19-6x-1 = -19x = 3
3x-2 = 2x+3 3x-2x = 3+2 x = 5
-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
To solve this, present the equation in the standard slope/intercept form of y = mx + c. 'm' is the slope. 2x + 5y = 10 5y = -2x + 10 y = -2/5x + 2 Therefore, -2/5 is the slope.
