Leo spent the same amount of time working on each of 5 different weight machines and then spent Two-thirds of an hour on the treadmill. If he spent a total of 1 and three-fourths hours at the gym, which shows the correct equation and solution for x, the number of hours Leo spent at each of the weight machines?
A) 5 x + 2/3 = 1 3/4; Leo spent 13 minutes at each machine.

B) 5 x + 2/3 = 1 3/4; Leo spent 29 minutes at each machine.

C) 2/3 x + 1 3/4 = 5; Leo spent 5 minutes at each machine.

D) 2/3 x + 1 3/4 = 5; Leo spent 10 minutes at each machine.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
