The lines y = 10x + 2 and y = 112 meet at x = 11. 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+2=11210x + 2 = 112
  2. 2

    Subtract 2 from both sides:

    10x+2−2=112−2 ⇒ 10x=11010x + 2 - 2 = 112 - 2 \ \Rightarrow\ 10x = 110
  3. 3

    Divide both sides by 10:

    10x10=11010 ⇒ x=11\frac{10x}{10} = \frac{110}{10} \ \Rightarrow\ x = 11
  4. 4

    Check: put x = 11 back into the equation.
