The answer is 7x = 6(x + 15)

x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours:  7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours:    6y = half of the floor
So: 7x = 6y

</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15

</span>7x = 6y
y = x + 15

Substitute the second equation into the first one:
7x = 6(x + 15)
