The lines y = 3x + 10 and y = 70 meet at x = 20. 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=703x + 10 = 70
  2. 2

    Subtract 10 from both sides:

    3x+10−10=70−10 ⇒ 3x=603x + 10 - 10 = 70 - 10 \ \Rightarrow\ 3x = 60
  3. 3

    Divide both sides by 3:

    3x3=603 ⇒ x=20\frac{3x}{3} = \frac{60}{3} \ \Rightarrow\ x = 20
  4. 4

    Check: put x = 20 back into the equation.
