OpenStudy (narissa):

sorry i dont how with fractions

OpenStudy (narissa):

@jim_thompson5910 can u explain how please

TheSmartOne (thesmartone):

Do you even know how to cross multiply?

OpenStudy (narissa):

2*2 =4x 3*2 =6x+y

OpenStudy (narissa):

u r smart i am not

TheSmartOne (thesmartone):

It's \(\sf 3 \times (2x+y)+ = 6x+3y\)

TheSmartOne (thesmartone):

So now we have: \(\sf 4x=6x+3y\) And they want to know what \(\sf\Large\frac{x}{y}=?\)

OpenStudy (narissa):

y=3

OpenStudy (narissa):

right?

OpenStudy (narissa):

so its 2/3 because 4-6=2

OpenStudy (narissa):

so its c

TheSmartOne (thesmartone):

\(\sf -2x=3y\) Divide -2 on both sides, and then divide y on both sides...

OpenStudy (narissa):

@TheSmartOne im in special ed for math and struggle sorry

OpenStudy (narissa):

oh wow its b -2/3

OpenStudy (narissa):
