Solve 6x + 9 = 33

The solution of 6x + 9 = 33 is x = 4.

The lines y = 6x + 9 and y = 33 meet at x = 4-2246810-1010203040506070x = 4y = 6x + 9y = 33
The lines y = 6x + 9 and y = 33 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.

    6x+9=336x + 9 = 33
  2. 2

    Subtract 9 from both sides:

    6x+9−9=33−9 ⇒ 6x=246x + 9 - 9 = 33 - 9 \ \Rightarrow\ 6x = 24
  3. 3

    Divide both sides by 6:

    6x6=246 ⇒ x=4\frac{6x}{6} = \frac{24}{6} \ \Rightarrow\ x = 4
  4. 4

    Check: put x = 4 back into the equation.
