Explain it step by step in chatMake a short video of it
The lines y = 5x + 7 and y = 67 meet at x = 12681012141618405060708090100x = 12y = 5x + 7y = 67
The lines y = 5x + 7 and y = 67 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.

    5x+7=675x + 7 = 67
  2. 2

    Subtract 7 from both sides:

    5x+7−7=67−7 ⇒ 5x=605x + 7 - 7 = 67 - 7 \ \Rightarrow\ 5x = 60
  3. 3

    Divide both sides by 5:

    5x5=605 ⇒ x=12\frac{5x}{5} = \frac{60}{5} \ \Rightarrow\ x = 12
  4. 4

    Check: put x = 12 back into the equation.
