Solve 5x āˆ’ 9 = āˆ’44

The solution of 5x āˆ’ 9 = āˆ’44 is x = -7.

The lines y = 5x āˆ’ 9 and y = -44 meet at x = -7-12-10-8-6-4-2-80-70-60-50-40-30-20-10x = -7y = 5x āˆ’ 9y = -44
The lines y = 5x āˆ’ 9 and y = -44 meet at x = -7. 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 subtraction, then the multiplication.

    5xāˆ’9=āˆ’445x - 9 = -44
  2. 2

    Add 9 to both sides:

    5xāˆ’9+9=āˆ’44+9 ⇒ 5x=āˆ’355x - 9 + 9 = -44 + 9 \ \Rightarrow\ 5x = -35
  3. 3

    Divide both sides by 5:

    5x5=āˆ’355 ⇒ x=āˆ’7\frac{5x}{5} = \frac{-35}{5} \ \Rightarrow\ x = -7
  4. 4

    Check: put x = -7 back into the equation.
