Explain it step by step in chatMake a short video of it
The lines y = 2x + 4 and y = 14 meet at x = 5246810510152025x = 5y = 2x + 4y = 14
The lines y = 2x + 4 and y = 14 meet at x = 5. 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+4=142x + 4 = 14
  2. 2

    Subtract 4 from both sides:

    2x+4−4=14−4 ⇒ 2x=102x + 4 - 4 = 14 - 4 \ \Rightarrow\ 2x = 10
  3. 3

    Divide both sides by 2:

    2x2=102 ⇒ x=5\frac{2x}{2} = \frac{10}{2} \ \Rightarrow\ x = 5
  4. 4

    Check: put x = 5 back into the equation.
