Explain it step by step in chatMake a short video of it
The lines y = 12x + 2 and y = 14 meet at x = 1-4-2246-60-40-2020406080100x = 1y = 12x + 2y = 14
The lines y = 12x + 2 and y = 14 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.

    12x+2=1412x + 2 = 14
  2. 2

    Subtract 2 from both sides:

    12x+2−2=14−2 ⇒ 12x=1212x + 2 - 2 = 14 - 2 \ \Rightarrow\ 12x = 12
  3. 3

    Divide both sides by 12:

    12x12=1212 ⇒ x=1\frac{12x}{12} = \frac{12}{12} \ \Rightarrow\ x = 1
  4. 4

    Check: put x = 1 back into the equation.
