Explain it step by step in chatMake a short video of it
The lines y = 2x + 6 and y = 26 meet at x = 1046810121416152025303540x = 10y = 2x + 6y = 26
The lines y = 2x + 6 and y = 26 meet at x = 10. 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+6=262x + 6 = 26
  2. 2

    Subtract 6 from both sides:

    2x+6−6=26−6 ⇒ 2x=202x + 6 - 6 = 26 - 6 \ \Rightarrow\ 2x = 20
  3. 3

    Divide both sides by 2:

    2x2=202 ⇒ x=10\frac{2x}{2} = \frac{20}{2} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
