The lines y = 10x + 8 and y = 158 meet at x = 15. 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.

    10x+8=15810x + 8 = 158
  2. 2

    Subtract 8 from both sides:

    10x+8−8=158−8 ⇒ 10x=15010x + 8 - 8 = 158 - 8 \ \Rightarrow\ 10x = 150
  3. 3

    Divide both sides by 10:

    10x10=15010 ⇒ x=15\frac{10x}{10} = \frac{150}{10} \ \Rightarrow\ x = 15
  4. 4

    Check: put x = 15 back into the equation.
