Explain it step by step in chatMake a short video of it
The lines y = 2x + 14 and y = 18 meet at x = 2-4-2246851015202530x = 2y = 2x + 14y = 18
The lines y = 2x + 14 and y = 18 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.

    2x+14=182x + 14 = 18
  2. 2

    Subtract 14 from both sides:

    2x+14−14=18−14 ⇒ 2x=42x + 14 - 14 = 18 - 14 \ \Rightarrow\ 2x = 4
  3. 3

    Divide both sides by 2:

    2x2=42 ⇒ x=2\frac{2x}{2} = \frac{4}{2} \ \Rightarrow\ x = 2
  4. 4

    Check: put x = 2 back into the equation.
