2.1.5 Solving Equations with Variables on Both Sides − Practice

1. Solve 48 p − 32 = 51 p − 65.

2. Solve 4 z + 7 + 2 z = 5 − z .

3. Determine the number of solutions for the equation. 8 m + 7 + 10 m = 4 + 18 m + 3

4. Solve the equation. 7(3 p − 4) = 4 p + 6

5. Solve the equation. + = a a (8 40) 7

6. Solve the equation.

5 − 2(3 z + 2) = − 4(1 − 2 z )
