this one is hard

i would go with b

BUT IM NOT SURE IF ITS 100% correct

so if you want to trust me, trust me.

but, i don’t trust myself on this one lol :)

tell me if you got it right.

the answer is x = 2

34/x = 17

multiply both sides by x

34/x x = 17x

multply 34/x

and it gives you 34 = 17x

then switch sides 17x = 34

divide both sides by 17

17x/17     34/17

and that gives you x = 2

The number 15 times 3 is equals 45.
