The lines y = 2x + 2 and y = 32 meet at x = 15. 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.

    2x+2=322x + 2 = 32
  2. 2

    Subtract 2 from both sides:

    2x+2−2=32−2 ⇒ 2x=302x + 2 - 2 = 32 - 2 \ \Rightarrow\ 2x = 30
  3. 3

    Divide both sides by 2:

    2x2=302 ⇒ x=15\frac{2x}{2} = \frac{30}{2} \ \Rightarrow\ x = 15
  4. 4

    Check: put x = 15 back into the equation.
