The solution of 9x + 1 = 37 is x = 4.

Explain it step by step in chatMake a short video of it
The lines y = 9x + 1 and y = 37 meet at x = 4-2246810-2020406080100x = 4y = 9x + 1y = 37
The lines y = 9x + 1 and y = 37 meet at x = 4. 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=379x + 1 = 37
  2. 2

    Subtract 1 from both sides:

    9x+1−1=37−1 ⇒ 9x=369x + 1 - 1 = 37 - 1 \ \Rightarrow\ 9x = 36
  3. 3

    Divide both sides by 9:

    9x9=369 ⇒ x=4\frac{9x}{9} = \frac{36}{9} \ \Rightarrow\ x = 4
  4. 4

    Check: put x = 4 back into the equation.

    9⋅4+1=36+1=37✓9\cdot4 + 1 = 36 + 1 = 37 \checkmark
