Explain it step by step in chatMake a short video of it
The lines y = 6x + 1 and y = 55 meet at x = 94681012142030405060708090x = 9y = 6x + 1y = 55
The lines y = 6x + 1 and y = 55 meet at x = 9. 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.

    6x+1=556x + 1 = 55
  2. 2

    Subtract 1 from both sides:

    6x+1−1=55−1 ⇒ 6x=546x + 1 - 1 = 55 - 1 \ \Rightarrow\ 6x = 54
  3. 3

    Divide both sides by 6:

    6x6=546 ⇒ x=9\frac{6x}{6} = \frac{54}{6} \ \Rightarrow\ x = 9
  4. 4

    Check: put x = 9 back into the equation.
