What is a system of the equation?

A system of equations is a set of two or more equations that you deal with at one time.

Let the length of the shorter piece be x.

And the length of the longer piece is 3x -2.

Greg has a piece of rope that is 18 ft long.

Then,

[tex]\rm \text{longest piece+shortest piece}=18\\\\x+3x-2=18\\\\4x=18+2\\\\4x=20\\\\x=\dfrac{20}{4}\\\\x=5[/tex]

Therefore,

The length of the shorter piece is x =5.

And the length of the longer piece = 3x -2 = 3(5)-2 = 15-2 = 13

Hence, the length of the shortest piece is 5, and the longest piece is 13 feet.
