Explain it step by step in chatMake a short video of it
The lines y = 6x + 2 and y = 38 meet at x = 6246810121020304050607080x = 6y = 6x + 2y = 38
The lines y = 6x + 2 and y = 38 meet at x = 6. 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+2=386x + 2 = 38
  2. 2

    Subtract 2 from both sides:

    6x+2−2=38−2 ⇒ 6x=366x + 2 - 2 = 38 - 2 \ \Rightarrow\ 6x = 36
  3. 3

    Divide both sides by 6:

    6x6=366 ⇒ x=6\frac{6x}{6} = \frac{36}{6} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
