isn’t number 5 C because it would be 10 divided by 5?

Thank you coach for this and I was about to comment about 5 too😂 of it being x/5=2

[stevenbecker]

for problem 3/3/5 you solved for X but the question is asking for x/5. Answer is 2 not 10.
Otherwise- great strategies (but make sure you read the question!) :-)

Please can u explain to me how u got 5/6 in the first question by simplifying ?

EDIT: oh it's LCD lol
It's 2 a.m. where I live so my brain is kinda slow atm :)

So for the first problem why are we choosing X=0 when the problem says that x>3

[aadityajindal]

Dude, it is clearly written in the first question that the values of x must be greater than 3. Then how can you take the value of x to be 0 and then solve to find the answer?
