-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
-7x + 6 + 7x - 2 = 4
The equation can be solved by isolating the variables from the numbers. The answer would be 4x = 8, which equals 2.
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
7x + 2 = 6x + 2 if and only x = 0.
7x + 2 = 5,6

7x+2-2=16-27x = 147x/7 = 14/7x = 2
7x is still the slope, no matter what x equals.
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
Subtract by 7x and divide by 2.
7x + 5y 7(3) + 5(2) 21 + 10 = 31
8x-2 = -9+7x8x-7x = -9+2x=-7
x=-7/13
7x + 2 = -4 7x + 2 - 2 = -4 - 2 7x = -6 7x/7 = -6/7 x = -6/7
x=1
