Explain it step by step in chatMake a short video of it
The lines y = 2x + 9 and y = 17 meet at x = 4-224681051015202530x = 4y = 2x + 9y = 17
The lines y = 2x + 9 and y = 17 meet at x = 4. 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+9=172x + 9 = 17
  2. 2

    Subtract 9 from both sides:

    2x+9−9=17−9 ⇒ 2x=82x + 9 - 9 = 17 - 9 \ \Rightarrow\ 2x = 8
  3. 3

    Divide both sides by 2:

    2x2=82 ⇒ x=4\frac{2x}{2} = \frac{8}{2} \ \Rightarrow\ x = 4
  4. 4

    Check: put x = 4 back into the equation.
