1. Solve for x. 8x - 5 = 3x + 20
2. Solve for x. 10x + 5 = 7x - 16
3. Solve for x. 13x + 24 = 3x - 26
4. Solve for x. -12x + 20 = -10x + 32
5. Solve for x. 5x + 2 = 3x - 20
1. Subtract both sides by 3x:
8x - 5 - 3x = 3x + 20 - 3x
5x - 5 = 20
2. Subtract both sides by 7x:
10x + 5 - 7x = 7x - 16 - 7x
3x + 5 = -16
3. Subtract both sides by 3x:
13x + 24 - 3x = 3x - 26 - 3x
10x + 24 = -26
4. Add 10x to both sides:
-12x + 20 + 10x = -10x + 32 + 10x
-2x + 20 = 32
5. Subtract both sides by 3x:
5x + 2 - 3x = 3x - 20 - 3x
2x + 2 = -20.
