\[25-\frac{ 3 }{ 7 }f=19+\frac{ 4 }{ 7 }f\] bring like terms 2gether

OpenStudy (anonymous):
add 3/7 f on both sides

OpenStudy (anonymous):
how do you add a fraction?

OpenStudy (anonymous):
\[25-\frac{ 3 }{ 7 }f+\frac{ 3 }{ 7 }f=19+\frac{ 4 }{ 7 }f+\frac{ 3 }{ 7 }f\]

take LCM

OpenStudy (anonymous):
huh :(

OpenStudy (anonymous):
\[25-19=\frac{ 4 }{ 7 }f+\frac{ 3 }{ 7 }f=\frac{ 4+3 }{ 7 }f=\frac{ 7 }{ 7 }f =f\] f=6, does dat help?

OpenStudy (anonymous):
u got common denominator in fraction just add the numerator

OpenStudy (anonymous):
i guess...

@lovemenplayhard help please :(
4c + 7 + 6c =23

OpenStudy (anonymous):
do i subtract here?

OpenStudy (anonymous):
add like terms
4c+6c+7=23
10c+7=23
subtract 7 both the sides
10c+7-7=23-7
10c=16

OpenStudy (anonymous):
later divide both da sides by 10\[\frac{ 10 c}{ 10 }=\frac{ 16 }{ 10 }=\frac{ 8 }{ 5 }=c\]
