The first side of a triangle is 8m shorter than the second side. the third side is 4 times a long as the first side. the perimeter is 26m. find the length of each side.

first side: x-8

2nd side: x

3rd side: 4(x-8)

write equation:

x+x-8+4(x-8)=26

x+x-8+4x-32=26

6x-40=26

add 40 to each side

6x=66

divide both sides by 6

x=11 2nd side

x-8=11-8=3 1st side

4(x-8)=4x-32=4(11)-32=44-32=12 3rd side

3, 11, & 12 are the 3 sides
