Explain it step by step in chatMake a short video of it
The lines y = 7x + 12 and y = 96 meet at x = 126810121416186080100120140x = 12y = 7x + 12y = 96
The lines y = 7x + 12 and y = 96 meet at x = 12. 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.

    7x+12=967x + 12 = 96
  2. 2

    Subtract 12 from both sides:

    7x+12−12=96−12 ⇒ 7x=847x + 12 - 12 = 96 - 12 \ \Rightarrow\ 7x = 84
  3. 3

    Divide both sides by 7:

    7x7=847 ⇒ x=12\frac{7x}{7} = \frac{84}{7} \ \Rightarrow\ x = 12
  4. 4

    Check: put x = 12 back into the equation.
