The lines y = 10x + 10 and y = 210 meet at x = 20. 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+10=21010x + 10 = 210
  2. 2

    Subtract 10 from both sides:

    10x+10−10=210−10 ⇒ 10x=20010x + 10 - 10 = 210 - 10 \ \Rightarrow\ 10x = 200
  3. 3

    Divide both sides by 10:

    10x10=20010 ⇒ x=20\frac{10x}{10} = \frac{200}{10} \ \Rightarrow\ x = 20
  4. 4

    Check: put x = 20 back into the equation.
