The lines y = 12x + 5 and y = 125 meet at x = 10. 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+5=12512x + 5 = 125
  2. 2

    Subtract 5 from both sides:

    12x+5−5=125−5 ⇒ 12x=12012x + 5 - 5 = 125 - 5 \ \Rightarrow\ 12x = 120
  3. 3

    Divide both sides by 12:

    12x12=12012 ⇒ x=10\frac{12x}{12} = \frac{120}{12} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
