Explain it step by step in chatMake a short video of it
The lines y = 2x + 2 and y = 14 meet at x = 624681012510152025x = 6y = 2x + 2y = 14
The lines y = 2x + 2 and y = 14 meet at x = 6. 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+2=142x + 2 = 14
  2. 2

    Subtract 2 from both sides:

    2x+2−2=14−2 ⇒ 2x=122x + 2 - 2 = 14 - 2 \ \Rightarrow\ 2x = 12
  3. 3

    Divide both sides by 2:

    2x2=122 ⇒ x=6\frac{2x}{2} = \frac{12}{2} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
