Explain it step by step in chatMake a short video of it
The lines y = 2x + 10 and y = 12 meet at x = 1-4-2246510152025x = 1y = 2x + 10y = 12
The lines y = 2x + 10 and y = 12 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+10=122x + 10 = 12
  2. 2

    Subtract 10 from both sides:

    2x+10−10=12−10 ⇒ 2x=22x + 10 - 10 = 12 - 10 \ \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.
