The lines y = 10x + 4 and y = 144 meet at x = 14. 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.

    10x+4=14410x + 4 = 144
  2. 2

    Subtract 4 from both sides:

    10x+4−4=144−4 ⇒ 10x=14010x + 4 - 4 = 144 - 4 \ \Rightarrow\ 10x = 140
  3. 3

    Divide both sides by 10:

    10x10=14010 ⇒ x=14\frac{10x}{10} = \frac{140}{10} \ \Rightarrow\ x = 14
  4. 4

    Check: put x = 14 back into the equation.
