Solve? 4/5y+2=6

OpenStudy (ash2326):

\[\frac 4 5 y+2=6\] Subtract both sides by 2, what would you get? \[\frac 4 5 y +2- 2= 6-2\]

OpenStudy (anonymous):

4/5 y= 4?

OpenStudy (ash2326):

Yes, good :D Now multiply both sides by 5

OpenStudy (anonymous):

how do i multiply a fraction by 5?

OpenStudy (ash2326):

\[\frac 4 5 y= 4\] \[(\frac 4 5 \times 5 ) y= 4\times 5\] \[(\frac 4 {\cancel 5} \times \cancel 5 ) y= 4\times 5\] \[4y=4\times 5\] Do you get this?

OpenStudy (ash2326):

@thatgirl666 ????

OpenStudy (anonymous):

Not really so the answer is 20?

OpenStudy (anonymous):

Nevermind. i then divide by 4 and it equals 5

OpenStudy (ash2326):

Yeah, let me explain you the multiplication of fractions

OpenStudy (anonymous):

Ok

OpenStudy (ash2326):

Suppose you have the fraction \[\frac a b \] You need to multiply by a no. say c \[\frac ab \times c=\frac{a\times b}c\] If you had to multiply by 1/c \[\frac ab \times \frac 1 c=\frac a {b\times c}\] here \[a \ne b \ne c\] Do you get this?

OpenStudy (anonymous):

Yes i do now Thank you

OpenStudy (ash2326):

If you multiply a/b by b, what would you get?

OpenStudy (ash2326):

\[\frac a b \times b= ???\]

OpenStudy (anonymous):

c

OpenStudy (ash2326):

We don't even have c in the expression \[\frac 2 4 \times 4=???\]
