Step-by-step explanation:

Step 1: Define

3(14 + x) = 57

Step 2: Solve for x

  1. [Distributive Property] Distribute 3:                                                                 42 + 3x = 57
  2. [Subtraction Property of Equality] Subtract 42 on both sides:                      3x = 15
  3. [Division Property of Equality] Divide 3 on both sides:                                  x = 5

Answer:

x=5

Step-by-step explanation:

First multiply 3(14+x) = 42 + 3x

Now you have the equation 42 + 3x =57

Then subtract 42 from both sides

The equation would be 3x = 15

Divide 3 from each side to get the x value

15/3=5

So therefore your answer would be x = 5

Hope this helps!
