Explain it step by step in chatMake a short video of it
The lines y = 8x + 5 and y = 29 meet at x = 3-22468-2020406080x = 3y = 8x + 5y = 29
The lines y = 8x + 5 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.

    8x+5=298x + 5 = 29
  2. 2

    Subtract 5 from both sides:

    8x+5−5=29−5 ⇒ 8x=248x + 5 - 5 = 29 - 5 \ \Rightarrow\ 8x = 24
  3. 3

    Divide both sides by 8:

    8x8=248 ⇒ x=3\frac{8x}{8} = \frac{24}{8} \ \Rightarrow\ x = 3
  4. 4

    Check: put x = 3 back into the equation.
