The lines y = 10x + 14 and y = 104 meet at x = 9. 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+14=10410x + 14 = 104
  2. 2

    Subtract 14 from both sides:

    10x+14−14=104−14 ⇒ 10x=9010x + 14 - 14 = 104 - 14 \ \Rightarrow\ 10x = 90
  3. 3

    Divide both sides by 10:

    10x10=9010 ⇒ x=9\frac{10x}{10} = \frac{90}{10} \ \Rightarrow\ x = 9
  4. 4

    Check: put x = 9 back into the equation.
