Answer 2

1. 2x+2-3x+5 = 3+2
2x -3x = 3+2-2-5
-1x = 5-7
1x = -2
X = -2/-1
X = 2

2. 2x+1-7x+1 = -2x+1+7x
2x-7x+2x-7x = 1-1-1
4x -14x = 1-2
-10x = -1
X = -1/-10
X = -0.1

3. 7x-3 = 3x+9
7x -3x = 9+3
4x = 12
X = 12/4
X= 3

4. 5x +3x = 8
8x = 8
X = 8/8
X = 1

5. 2-x = x-8
-x -x = -8 -2
-2x = -10
X = -10/-2
X = 5
