Answer:
1. x = 10 2. x = 7 3. x = 1 4. x = 6
Explanation:
1. -2x + 81 = 61 (Subtract 81 from 61)
-2x = -20 (Divide)
x = 10
2. 9x - 58 = 5 (Add 58 to 5)
9x = 63 (Divide)
x = 7
3. 21 +10x = 3x + 28 (Rearrange expression)
21 - 28 = 3x - 10x (Combine like terms)
-7 = -7x (Divide)
x = 1
4. 9x - 42 = 2x (Rearrange)
9x - 2x = 42 (Combine like terms)
7x = 42 (Divide)
x = 6
