The lines y = 12x + 4 and y = 196 meet at x = 16. 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.

    12x+4=19612x + 4 = 196
  2. 2

    Subtract 4 from both sides:

    12x+4−4=196−4 ⇒ 12x=19212x + 4 - 4 = 196 - 4 \ \Rightarrow\ 12x = 192
  3. 3

    Divide both sides by 12:

    12x12=19212 ⇒ x=16\frac{12x}{12} = \frac{192}{12} \ \Rightarrow\ x = 16
  4. 4

    Check: put x = 16 back into the equation.
