Solve 9x + 10 = 1

The solution of 9x + 10 = 1 is x = -1.

Explain it step by step in chatMake a short video of it
The lines y = 9x + 10 and y = 1 meet at x = -1-6-4-224-60-40-20204060x = -1y = 9x + 10y = 1
The lines y = 9x + 10 and y = 1 meet at x = -1. 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+10=19x + 10 = 1
  2. 2

    Subtract 10 from both sides:

    9x+10−10=1−10 ⇒ 9x=−99x + 10 - 10 = 1 - 10 \ \Rightarrow\ 9x = -9
  3. 3

    Divide both sides by 9:

    9x9=−99 ⇒ x=−1\frac{9x}{9} = \frac{-9}{9} \ \Rightarrow\ x = -1
  4. 4

    Check: put x = -1 back into the equation.

    9⋅(−1)+10=−9+10=1✓9\cdot(-1) + 10 = -9 + 10 = 1 \checkmark
