Answer:

x = 1

Explanation:

3(3x + 2) = 13 + 5 - 4x + 1 Distribute the 3

3(3x) + 3(2) = 13 + 5 - 4x + 1

9x + 6 = 13 + 5 - 4x + 1 Combine like terms

9x + 6 = 19 - 4x Add 4x to both sides

13x + 6 = 19 Subtract 6 from both sides

13x = 13 Divide both sides by 13

x = 1

Check:

Substitute 1 for x

3(3x + 2) = 13x + 5 - 4x + 1

3[(3)(1) + 2] = 13(1) + 5 -4(1) + 1

3(3 + 2) = 13 + 5 - 4 + 1

3(5) = 18 - 4 + 1

15 = 14 + 1

15 = 15 checks
