Explain it step by step in chatMake a short video of it
The lines y = 10x + 6 and y = 86 meet at x = 8246810121420406080100120140x = 8y = 10x + 6y = 86
The lines y = 10x + 6 and y = 86 meet at x = 8. 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.

    10x+6=8610x + 6 = 86
  2. 2

    Subtract 6 from both sides:

    10x+6−6=86−6 ⇒ 10x=8010x + 6 - 6 = 86 - 6 \ \Rightarrow\ 10x = 80
  3. 3

    Divide both sides by 10:

    10x10=8010 ⇒ x=8\frac{10x}{10} = \frac{80}{10} \ \Rightarrow\ x = 8
  4. 4

    Check: put x = 8 back into the equation.
