There are 127 lbs of fruits in the store: apples, oranges, and peaches. there are four times as many apples as there are peaches, and 7 lbs more oranges than peaches. how many apples, oranges, and peaches are there in the store?

Let
x> amount of pounds of apples
y> amount of pounds of oranges
z> amount of pounds of peaches

we know that
x+y+z=127> equation 1
x=4z> equation 2
y=7+z> equation 3

substitute  equation 2 and equation 3 in equation 1
x+y+z=127> (4z)+(7+z)+z=127---> 6z=127-7---> 6z=120> z=20 lb
x=4z---> x=4*20> x=80 lb
y=7+z> y=7+20---> y=27 lb

 amount of pounds of apples> 80 lb
amount of pounds of oranges> 27 lb
amount of pounds of peaches---> 20 lb

Its d so thats how it would would back from 1.0 form three four two
