Solve 8x + 12 = 4

The solution of 8x + 12 = 4 is x = -1.

Explain it step by step in chatMake a short video of it
The lines y = 8x + 12 and y = 4 meet at x = -1-6-4-224-40-20204060x = -1y = 8x + 12y = 4
The lines y = 8x + 12 and y = 4 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.

    8x+12=48x + 12 = 4
  2. 2

    Subtract 12 from both sides:

    8x+12−12=4−12 ⇒ 8x=−88x + 12 - 12 = 4 - 12 \ \Rightarrow\ 8x = -8
  3. 3

    Divide both sides by 8:

    8x8=−88 ⇒ x=−1\frac{8x}{8} = \frac{-8}{8} \ \Rightarrow\ x = -1
  4. 4

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

    8⋅(−1)+12=−8+12=4✓8\cdot(-1) + 12 = -8 + 12 = 4 \checkmark
