Answer:

4

Step-by-step explanation:

3x + 2(x + 4) + 2x+1 = 37                    Remove the brackets.

3x + 2x + 8 + 2x + 1 = 37                   Collect like terms

7x + 9 = 37                                         Subtract 9 from both sides

7x + 9-9 = 37 - 9                                Combine

7x = 28                                               Divide by 7

7x / 7 = 28/7

x = 4
