The lines y = 10x + 7 and y = 147 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.

    10x+7=14710x + 7 = 147
  2. 2

    Subtract 7 from both sides:

    10x+7−7=147−7 ⇒ 10x=14010x + 7 - 7 = 147 - 7 \ \Rightarrow\ 10x = 140
  3. 3

    Divide both sides by 10:

    10x10=14010 ⇒ x=14\frac{10x}{10} = \frac{140}{10} \ \Rightarrow\ x = 14
  4. 4

    Check: put x = 14 back into the equation.
