The lines y = 10x + 11 and y = 201 meet at x = 19. 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+11=20110x + 11 = 201
  2. 2

    Subtract 11 from both sides:

    10x+11−11=201−11 ⇒ 10x=19010x + 11 - 11 = 201 - 11 \ \Rightarrow\ 10x = 190
  3. 3

    Divide both sides by 10:

    10x10=19010 ⇒ x=19\frac{10x}{10} = \frac{190}{10} \ \Rightarrow\ x = 19
  4. 4

    Check: put x = 19 back into the equation.
