3.) -3x + 2 = 7(x + 5) + 34
-3x +2 = 7x+35 = 34
-3x -7x = 34 -2 +35
-10x = 67
x= 67/-10
..................
4.) 3x-4 = x/(-2) – 6
Multiply all by -2
-6x +8 = x +3
-6x -x = -8+3
-7x = -5
x= -5/-7 = 5/7
When a value changes sides, change the sign.

1.) You start with: 3x+7 - 8(x+2) = - 36
Use distribution rule: 3x+7 - 8x - 16 = - 36
Add the x'es together and the constants together: -5x - 9 = -36
Isolate the x: -5x = -27
Solve using division: x = 5.4
See if you can use these steps to solve the rest of them.
