The lines y = 12x + 10 and y = 94 meet at x = 7. 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=9412x + 10 = 94
  2. 2

    Subtract 10 from both sides:

    12x+10−10=94−10 ⇒ 12x=8412x + 10 - 10 = 94 - 10 \ \Rightarrow\ 12x = 84
  3. 3

    Divide both sides by 12:

    12x12=8412 ⇒ x=7\frac{12x}{12} = \frac{84}{12} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
