The lines y = 7x + 6 and y = 118 meet at x = 16. 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.

    7x+6=1187x + 6 = 118
  2. 2

    Subtract 6 from both sides:

    7x+6−6=118−6 ⇒ 7x=1127x + 6 - 6 = 118 - 6 \ \Rightarrow\ 7x = 112
  3. 3

    Divide both sides by 7:

    7x7=1127 ⇒ x=16\frac{7x}{7} = \frac{112}{7} \ \Rightarrow\ x = 16
  4. 4

    Check: put x = 16 back into the equation.
