6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11

x = -1.2, y = -3
If as a straight line equation: 5x+2y = 20 then y = -2.5x+10 whereas -2.5 is the slope and 10 is the y intercept
x=35
6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
3x-4=5x+6 gives: 2x=-10 which gives x=-5

3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
x = -1.2, y = -3
