Question

Solve : 3X + 3x + 1 + 3x + 2 = 39​

Answer 1

x = 4

Explanation:

combine all of the 3x first to get:

9x + 1 + 2 = 39

9x + 3 = 39

subtract 3 from both sides:

9x = 36

divide by 9

x = 4

Answer 2

Explanation:

`3x + 3x + 1 + 3x + 2 = 39 \\ 9x + 3 = 39 \\ 9x = 39 - 3 \\ 9x = 36 \\ x = (36)/(9) \\ x = 4`
