The lines y = 3x + 10 and y = 67 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.

    3x+10=673x + 10 = 67
  2. 2

    Subtract 10 from both sides:

    3x+10−10=67−10 ⇒ 3x=573x + 10 - 10 = 67 - 10 \ \Rightarrow\ 3x = 57
  3. 3

    Divide both sides by 3:

    3x3=573 ⇒ x=19\frac{3x}{3} = \frac{57}{3} \ \Rightarrow\ x = 19
  4. 4

    Check: put x = 19 back into the equation.
