The lines y = 4x + 7 and y = 67 meet at x = 15101214161820405060708090x = 15y = 4x + 7y = 67
The lines y = 4x + 7 and y = 67 meet at x = 15. 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.

    4x+7=674x + 7 = 67
  2. 2

    Subtract 7 from both sides:

    4x+7−7=67−7 ⇒ 4x=604x + 7 - 7 = 67 - 7 \ \Rightarrow\ 4x = 60
  3. 3

    Divide both sides by 4:

    4x4=604 ⇒ x=15\frac{4x}{4} = \frac{60}{4} \ \Rightarrow\ x = 15
  4. 4

    Check: put x = 15 back into the equation.
