Explain it step by step in chatMake a short video of it
The lines y = 2x + 8 and y = 22 meet at x = 724681012101520253035x = 7y = 2x + 8y = 22
The lines y = 2x + 8 and y = 22 meet at x = 7. 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+8=222x + 8 = 22
  2. 2

    Subtract 8 from both sides:

    2x+8−8=22−8 ⇒ 2x=142x + 8 - 8 = 22 - 8 \ \Rightarrow\ 2x = 14
  3. 3

    Divide both sides by 2:

    2x2=142 ⇒ x=7\frac{2x}{2} = \frac{14}{2} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
