The lines y = 11x + 4 and y = 103 meet at x = 9. 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.

    11x+4=10311x + 4 = 103
  2. 2

    Subtract 4 from both sides:

    11x+4−4=103−4 ⇒ 11x=9911x + 4 - 4 = 103 - 4 \ \Rightarrow\ 11x = 99
  3. 3

    Divide both sides by 11:

    11x11=9911 ⇒ x=9\frac{11x}{11} = \frac{99}{11} \ \Rightarrow\ x = 9
  4. 4

    Check: put x = 9 back into the equation.

    11⋅9+4=99+4=103✓11\cdot9 + 4 = 99 + 4 = 103 \checkmark
