The lines y = 12x + 10 and y = 70 meet at x = 5. 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.

    12x+10=7012x + 10 = 70
  2. 2

    Subtract 10 from both sides:

    12x+10−10=70−10 ⇒ 12x=6012x + 10 - 10 = 70 - 10 \ \Rightarrow\ 12x = 60
  3. 3

    Divide both sides by 12:

    12x12=6012 ⇒ x=5\frac{12x}{12} = \frac{60}{12} \ \Rightarrow\ x = 5
  4. 4

    Check: put x = 5 back into the equation.
