The lines y = 7x + 2 and y = 135 meet at x = 19. 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+2=1357x + 2 = 135
  2. 2

    Subtract 2 from both sides:

    7x+2−2=135−2 ⇒ 7x=1337x + 2 - 2 = 135 - 2 \ \Rightarrow\ 7x = 133
  3. 3

    Divide both sides by 7:

    7x7=1337 ⇒ x=19\frac{7x}{7} = \frac{133}{7} \ \Rightarrow\ x = 19
  4. 4

    Check: put x = 19 back into the equation.
