Explain it step by step in chatMake a short video of it
The lines y = 2x + 4 and y = 26 meet at x = 116810121416152025303540x = 11y = 2x + 4y = 26
The lines y = 2x + 4 and y = 26 meet at x = 11. 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=262x + 4 = 26
  2. 2

    Subtract 4 from both sides:

    2x+4−4=26−4 ⇒ 2x=222x + 4 - 4 = 26 - 4 \ \Rightarrow\ 2x = 22
  3. 3

    Divide both sides by 2:

    2x2=222 ⇒ x=11\frac{2x}{2} = \frac{22}{2} \ \Rightarrow\ x = 11
  4. 4

    Check: put x = 11 back into the equation.
