The lines y = 4x + 10 and y = 66 meet at x = 14. 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.

    4x+10=664x + 10 = 66
  2. 2

    Subtract 10 from both sides:

    4x+10−10=66−10 ⇒ 4x=564x + 10 - 10 = 66 - 10 \ \Rightarrow\ 4x = 56
  3. 3

    Divide both sides by 4:

    4x4=564 ⇒ x=14\frac{4x}{4} = \frac{56}{4} \ \Rightarrow\ x = 14
  4. 4

    Check: put x = 14 back into the equation.
