Solve 6x + 3 = 9

The solution of 6x + 3 = 9 is x = 1.

Explain it step by step in chatMake a short video of it
The lines y = 6x + 3 and y = 9 meet at x = 1-4-2246-30-20-101020304050x = 1y = 6x + 3y = 9
The lines y = 6x + 3 and y = 9 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.

    6x+3=96x + 3 = 9
  2. 2

    Subtract 3 from both sides:

    6x+3−3=9−3 ⇒ 6x=66x + 3 - 3 = 9 - 3 \ \Rightarrow\ 6x = 6
  3. 3

    Divide both sides by 6:

    6x6=66 ⇒ x=1\frac{6x}{6} = \frac{6}{6} \ \Rightarrow\ x = 1
  4. 4

    Check: put x = 1 back into the equation.
