An equation will have infinite solutions if both sides of the equal sign are the exact same thing, for instance $4x+4=4x+4$ . (You can test this with any value of x and find that they all work!)

So to find the equations that have infinite solutions, we need to see which have the same exact sides.

$37x-37 = 37x-37$ have the same thing on each side: $37x-37\\$ , so this has infinite solutions.

$74x-37 = 74-37$ does not have the same thing on each side, so it doesn’t have infinite solutions (it has 1)

$73x-37 = 73x-37$ has the same thing on each side: $73x-37$ , so this has infinite solutions.

And finally, $x-37=x-37$ has the same thing on each side: $x-37$ , so it has infinite solutions.

Hope this helped!

Traveling at 65 miles per hour, how many minutes, rounded to the nearest whole number, does it take to drive 125 miles from San

DENIUS [597]

$1h=60min\\\\65\ mi\ -\ 1\ h=60\ min\\\\125\ mi-\ x\ min\\\\cross\ multiply\\\\65\cdot x=125\cdot60\\\\65x=7500\ \ \ |divide\ both\ sides\ by\ 65\\\\x=\dfrac{7500}{65}\approx115\\\\Answer:\boxed{115\ min}$
