Explain it step by step in chatMake a short video of it
The lines y = 9x + 8 and y = 62 meet at x = 62468101220406080100120x = 6y = 9x + 8y = 62
The lines y = 9x + 8 and y = 62 meet at x = 6. 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+8=629x + 8 = 62
  2. 2

    Subtract 8 from both sides:

    9x+8−8=62−8 ⇒ 9x=549x + 8 - 8 = 62 - 8 \ \Rightarrow\ 9x = 54
  3. 3

    Divide both sides by 9:

    9x9=549 ⇒ x=6\frac{9x}{9} = \frac{54}{9} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
