The perimeter of the rectangle below is 54 units. Find the value of x

Answer: x=5
Step-by-step explanation:
3x appears two times and so does 2x +2. That created the equation 3x + 3x + 2x + 2 + 2x + 2=54. Combine like terms. You get 10x +4=54. Then you solve. Inverse operation: You subtract 4 from 54. Which is 50, then divide by 10. X=5
