Solve 5x + 2 = 22

The solution of 5x + 2 = 22 is x = 4.

The lines y = 5x + 2 and y = 22 meet at x = 4-2246810-101020304050x = 4y = 5x + 2y = 22
The lines y = 5x + 2 and y = 22 meet at x = 4. 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+2=225x + 2 = 22
  2. 2

    Subtract 2 from both sides:

    5x+2−2=22−2 ⇒ 5x=205x + 2 - 2 = 22 - 2 \ \Rightarrow\ 5x = 20
  3. 3

    Divide both sides by 5:

    5x5=205 ⇒ x=4\frac{5x}{5} = \frac{20}{5} \ \Rightarrow\ x = 4
  4. 4

    Check: put x = 4 back into the equation.
