Solve 5x + 10 = 70

The solution of 5x + 10 = 70 is x = 12.

The lines y = 5x + 10 and y = 70 meet at x = 12681012141618405060708090100x = 12y = 5x + 10y = 70
The lines y = 5x + 10 and y = 70 meet at x = 12. 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+10=705x + 10 = 70
  2. 2

    Subtract 10 from both sides:

    5x+10−10=70−10 ⇒ 5x=605x + 10 - 10 = 70 - 10 \ \Rightarrow\ 5x = 60
  3. 3

    Divide both sides by 5:

    5x5=605 ⇒ x=12\frac{5x}{5} = \frac{60}{5} \ \Rightarrow\ x = 12
  4. 4

    Check: put x = 12 back into the equation.
