The lines y = 2x + 10 and y = 34 meet at x = 12. 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+10=342x + 10 = 34
  2. 2

    Subtract 10 from both sides:

    2x+10−10=34−10 ⇒ 2x=242x + 10 - 10 = 34 - 10 \ \Rightarrow\ 2x = 24
  3. 3

    Divide both sides by 2:

    2x2=242 ⇒ x=12\frac{2x}{2} = \frac{24}{2} \ \Rightarrow\ x = 12
  4. 4

    Check: put x = 12 back into the equation.
