The lines y = 2x + 2 and y = 34 meet at x = 16. 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=342x + 2 = 34
  2. 2

    Subtract 2 from both sides:

    2x+2−2=34−2 ⇒ 2x=322x + 2 - 2 = 34 - 2 \ \Rightarrow\ 2x = 32
  3. 3

    Divide both sides by 2:

    2x2=322 ⇒ x=16\frac{2x}{2} = \frac{32}{2} \ \Rightarrow\ x = 16
  4. 4

    Check: put x = 16 back into the equation.
