Solve 8x + 3 = 3

The solution of 8x + 3 = 3 is x = 0.

Explain it step by step in chatMake a short video of it
The lines y = 8x + 3 and y = 3 meet at x = 0-6-4-2246-40-20204060x = 0y = 8x + 3y = 3
The lines y = 8x + 3 and y = 3 meet at x = 0. 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.

    8x+3=38x + 3 = 3
  2. 2

    Subtract 3 from both sides:

    8x+3−3=3−3 ⇒ 8x=08x + 3 - 3 = 3 - 3 \ \Rightarrow\ 8x = 0
  3. 3

    Divide both sides by 8:

    8x8=08 ⇒ x=0\frac{8x}{8} = \frac{0}{8} \ \Rightarrow\ x = 0
  4. 4

    Check: put x = 0 back into the equation.
