Question

Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of your work.

Part A: 5 + x^2 = 2x^2 + 13
Part B: 5 + x^3 = 2x^3 + 13

Answer 1

Part A:5=2x^2-x^2+13

5=x^2+13

0=x^2+13-5

0=x^2+8

Part B:5=2x^3-x^3+13

5=x^3+13

0=x^3+13-5

0=x^3+8

Explanation:

Answer 2

Part A:5=2x^2-x^2+13
5=x^2+13
0=x^2+13-5
0=x^2+8

Part B:5=2x^3-x^3+13
5=x^3+13
0=x^3+13-5
0=x^3+8
