X - shorter piece
3x - 2 - longer piece
x + 3x -2 = 18
x + 3x = 18 +2
4x = 20 | : 4
x=5
3*5 -2 = 15 - 2 = 13
shorter piece: 5 ft
longer piece : 13 ft
I hope this helps
First, you have to distribute the -1 throughout the parentheses, which gives you 7x-3x-10=-46.
Then, you combine 7x and -3x, which gives you 4x-10=-46.
Then, you add 10 to both sides of the equation, which gives you 4x=-36.
FInally, you divide both sides of the equation by 4, which gives you x=-9.
