Explain it step by step in chatMake a short video of it
The lines y = 9x + 2 and y = 29 meet at x = 3-22468-2020406080x = 3y = 9x + 2y = 29
The lines y = 9x + 2 and y = 29 meet at x = 3. 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.

    9x+2=299x + 2 = 29
  2. 2

    Subtract 2 from both sides:

    9x+2−2=29−2 ⇒ 9x=279x + 2 - 2 = 29 - 2 \ \Rightarrow\ 9x = 27
  3. 3

    Divide both sides by 9:

    9x9=279 ⇒ x=3\frac{9x}{9} = \frac{27}{9} \ \Rightarrow\ x = 3
  4. 4

    Check: put x = 3 back into the equation.
