4x+y=26 replace y with (x-4) & solve for x in this equation.
4x+(x-4)=26
4x+x=26+4
5x=30
x=30/5 <span>
x=6 answer.
y=6-4
y=2 answer.
Proof.
4*6+2=26
24=2=26
</span>26=26 <span>Y=x-4

48=4% loaded on truck and they have 96% left to load
So set up a proportion and it should look like this
48 over x = 4 over 100
48/x=4/100
Do cross multiplication 100×48= 4,800÷ 4 = 1,200 total on truck
