Solve 9x + 1 = 127

The solution of 9x + 1 = 127 is x = 14.

The lines y = 9x + 1 and y = 127 meet at x = 14810121416182080100120140160180x = 14y = 9x + 1y = 127
The lines y = 9x + 1 and y = 127 meet at x = 14. 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+1=1279x + 1 = 127
  2. 2

    Subtract 1 from both sides:

    9x+1−1=127−1 ⇒ 9x=1269x + 1 - 1 = 127 - 1 \ \Rightarrow\ 9x = 126
  3. 3

    Divide both sides by 9:

    9x9=1269 ⇒ x=14\frac{9x}{9} = \frac{126}{9} \ \Rightarrow\ x = 14
  4. 4

    Check: put x = 14 back into the equation.
