The lines y = 5x + 6 and y = 76 meet at x = 14. 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.

    5x+6=765x + 6 = 76
  2. 2

    Subtract 6 from both sides:

    5x+6−6=76−6 ⇒ 5x=705x + 6 - 6 = 76 - 6 \ \Rightarrow\ 5x = 70
  3. 3

    Divide both sides by 5:

    5x5=705 ⇒ x=14\frac{5x}{5} = \frac{70}{5} \ \Rightarrow\ x = 14
  4. 4

    Check: put x = 14 back into the equation.
