The lines y = 9x + 11 and y = 146 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.

    9x+11=1469x + 11 = 146
  2. 2

    Subtract 11 from both sides:

    9x+11−11=146−11 ⇒ 9x=1359x + 11 - 11 = 146 - 11 \ \Rightarrow\ 9x = 135
  3. 3

    Divide both sides by 9:

    9x9=1359 ⇒ x=15\frac{9x}{9} = \frac{135}{9} \ \Rightarrow\ x = 15
  4. 4

    Check: put x = 15 back into the equation.

    9⋅15+11=135+11=146✓9\cdot15 + 11 = 135 + 11 = 146 \checkmark
