Answer:

x = 3

Step-by-step explanation:

To solve this equation, we can use basic algebraic techniques as illustrated.

3(x + 4) = 7x Distribute the 3.

3x + 12 = 7x Subtract 3x from both sides of the equation.

12 = 4x Rearrange the equation so the variables are on the left.

4x = 12 Divide by 4 on both sides of the equation.

x = 3

Answer:

  • 3(x+4)=7x
  • 3x+12=7x
  • 7x=3x+12
  • 7x-3x=12
  • 4x=12
  • x=12/4
  • x=3
