Explain it step by step in chatMake a short video of it
The lines y = 6x + 8 and y = 74 meet at x = 116810121416405060708090100110x = 11y = 6x + 8y = 74
The lines y = 6x + 8 and y = 74 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.

    6x+8=746x + 8 = 74
  2. 2

    Subtract 8 from both sides:

    6x+8−8=74−8 ⇒ 6x=666x + 8 - 8 = 74 - 8 \ \Rightarrow\ 6x = 66
  3. 3

    Divide both sides by 6:

    6x6=666 ⇒ x=11\frac{6x}{6} = \frac{66}{6} \ \Rightarrow\ x = 11
  4. 4

    Check: put x = 11 back into the equation.
