Explain it step by step in chatMake a short video of it
The lines y = 2x + 12 and y = 14 meet at x = 1-4-2246510152025x = 1y = 2x + 12y = 14
The lines y = 2x + 12 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.

    2x+12=142x + 12 = 14
  2. 2

    Subtract 12 from both sides:

    2x+12−12=14−12 ⇒ 2x=22x + 12 - 12 = 14 - 12 \ \Rightarrow\ 2x = 2
  3. 3

    Divide both sides by 2:

    2x2=22 ⇒ x=1\frac{2x}{2} = \frac{2}{2} \ \Rightarrow\ x = 1
  4. 4

    Check: put x = 1 back into the equation.
