Explain it step by step in chatMake a short video of it
The lines y = 5x + 12 and y = 67 meet at x = 116810121416405060708090100x = 11y = 5x + 12y = 67
The lines y = 5x + 12 and y = 67 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.

    5x+12=675x + 12 = 67
  2. 2

    Subtract 12 from both sides:

    5x+12−12=67−12 ⇒ 5x=555x + 12 - 12 = 67 - 12 \ \Rightarrow\ 5x = 55
  3. 3

    Divide both sides by 5:

    5x5=555 ⇒ x=11\frac{5x}{5} = \frac{55}{5} \ \Rightarrow\ x = 11
  4. 4

    Check: put x = 11 back into the equation.
