Explain it step by step in chatMake a short video of it
The lines y = 8x + 2 and y = 50 meet at x = 62468101220406080100x = 6y = 8x + 2y = 50
The lines y = 8x + 2 and y = 50 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.

    8x+2=508x + 2 = 50
  2. 2

    Subtract 2 from both sides:

    8x+2−2=50−2 ⇒ 8x=488x + 2 - 2 = 50 - 2 \ \Rightarrow\ 8x = 48
  3. 3

    Divide both sides by 8:

    8x8=488 ⇒ x=6\frac{8x}{8} = \frac{48}{8} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
