The lines y = 4x + 4 and y = 56 meet at x = 13. The solution of the equation is the x-coordinate of the point where the two sides are equal.

How to work it out

  1. 1

    The goal is to get x alone. Undo the operations in the opposite order: first the addition, then the multiplication.

    4x+4=564x + 4 = 56
  2. 2

    Subtract 4 from both sides:

    4x+4−4=56−4 ⇒ 4x=524x + 4 - 4 = 56 - 4 \ \Rightarrow\ 4x = 52
  3. 3

    Divide both sides by 4:

    4x4=524 ⇒ x=13\frac{4x}{4} = \frac{52}{4} \ \Rightarrow\ x = 13
  4. 4

    Check: put x = 13 back into the equation.
