Question

Solve for u. -3/2-3/5u=-7/3

Answer 1

Add 3/2 to both sides.

-3/5u = -5/6
Multiply both sides by -5/3

u = 25/18

Answer 2

-3/5u = -7/3 + 3/2 = -5/6; cross multiply: -3*6 = 5u*-5; -18 = 5u*-5; 5u = -18/-25 = 18/25

Answer 3

Hope that helps!

Answer 4

I am pretty sure it is 18/25, not 25/18

Answer 5

Try plugging in 25/18 into the equation and see if you get -7/3 :)

Answer 6

hey can you help me understand where I went wrong? I get that you are right :-D

Answer 7

You put the variable in the denominator while cross multiplying rather than in the numerator.

Answer 8

Oh I know what happened. I took u as being in the denominator. I depends on what the original problem was.
