Question

A wire 14 cm long is cut into two pieces. The longer piece is 4 cm longer than the shorter piece. Find the length of the shorter piece of wire

Answer 1

5cm

Explanation:

Let x represent the shorter wire

if the shorter wire = x

therefore the longer wire = x+4

Write an equation

`x + x + 4 = 14`

Subtract 4 from both sides

`x + x + 4 - 4 = 14 - 4`

`x + x = 10`

`2x = 10`

Divide both sides by 2

`(2x)/(2) = (10)/(2)`

`x = 5`
