The solution of 5x + 10 = 20 is x = 2.

Explain it step by step in chatMake a short video of it
The lines y = 5x + 10 and y = 20 meet at x = 2-4-22468-101020304050x = 2y = 5x + 10y = 20
The lines y = 5x + 10 and y = 20 meet at x = 2. 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=205x + 10 = 20
  2. 2

    Subtract 10 from both sides:

    5x+10−10=20−10 ⇒ 5x=105x + 10 - 10 = 20 - 10 \ \Rightarrow\ 5x = 10
  3. 3

    Divide both sides by 5:

    5x5=105 ⇒ x=2\frac{5x}{5} = \frac{10}{5} \ \Rightarrow\ x = 2
  4. 4

    Check: put x = 2 back into the equation.
