Solve 2x + 11 = 17

The solution of 2x + 11 = 17 is x = 3.

The lines y = 2x + 11 and y = 17 meet at x = 3-2246851015202530x = 3y = 2x + 11y = 17
The lines y = 2x + 11 and y = 17 meet at x = 3. 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.

    2x+11=172x + 11 = 17
  2. 2

    Subtract 11 from both sides:

    2x+11−11=17−11 ⇒ 2x=62x + 11 - 11 = 17 - 11 \ \Rightarrow\ 2x = 6
  3. 3

    Divide both sides by 2:

    2x2=62 ⇒ x=3\frac{2x}{2} = \frac{6}{2} \ \Rightarrow\ x = 3
  4. 4

    Check: put x = 3 back into the equation.
