Answer:
x = (29-3y)/7
Step-by-step explanation:
7x + 3y =29
Solve for x
Subtract 3 y from each side
7x+3y-3y = 29-3y
7x = 29-3y
Divide each side by 7
7x/7 = (29-3y)/7
x = (29-3y)/7
Answer:
Two more people.
Step-by-step explanation:
If 4 people can mow a lawn in 6 hours, then 4 people can mow 1/6 of a lawn in 1 hour.
If 4 people can mow 1/6 of a lawn in 1 hour, then 1 person can mow 1/24 of a lawn in 1 hour.
If 1 person can mow 1/24 of a lawn in 1 hour, then 6 people can mow 1/4 of a lawn in 1 hour.
If 6 people can mow 1/4 of a lawn in 1 hour, then 6 people can mow a lawn in 4 hours.
6 people minus 4 people is 2 people.
