Using the graphing you graph the two equations and then find the point where the two lines of the equation meet.
Hope this helps :)
Hey there,
Let's say that the first piece is x cm
1st = x
2nd = x + 25%
3rd = x - 25%
100% = 240 cm
1% = 240 / 100
= 2.4cm
x + x + 25 + x - 25 = 100
3x + 25 - 25 = 100
3x = 100 - 25 + 25
3x = 100
3x = 240 cm
x = 240 / 3
= 80 cm
1st piece = 80 cm
2nd piece = 80 + (25% x 80)
= 80 + 20
= 100cm
3rd piece = 80 cm - (25% x 80)
= 80 cm - 20
= 60cm
Hope this helps :))
