Explain it step by step in chatMake a short video of it
The lines y = 2x + 2 and y = 24 meet at x = 116810121416101520253035x = 11y = 2x + 2y = 24
The lines y = 2x + 2 and y = 24 meet at x = 11. 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=242x + 2 = 24
  2. 2

    Subtract 2 from both sides:

    2x+2−2=24−2 ⇒ 2x=222x + 2 - 2 = 24 - 2 \ \Rightarrow\ 2x = 22
  3. 3

    Divide both sides by 2:

    2x2=222 ⇒ x=11\frac{2x}{2} = \frac{22}{2} \ \Rightarrow\ x = 11
  4. 4

    Check: put x = 11 back into the equation.
