Answer 4

Oh! Yeah! I do.

Answer 5

ok.... so....lemme do it by .... getting rid of the denominator....

what would be the result of \(\bf 3\times \cfrac{2}{3}
\)

Answer 6

ohhh ok, let's use the LCD then.... what's the LCD of the numbers 3 and 6 ?

Answer 7

6

Answer 8

okk...let us use that then \(\bf 10 = \cfrac{c}{3}-4+\cfrac{c}{6}\implies 10+4=\cfrac{c}{3}+\cfrac{c}{6}\qquad \color{blue}{LCD =6\quad thus}\\ \quad \\
14=\cfrac{2c+c}{6}\implies 14=\cfrac{3c}{6}\quad \textit{multiply by 6 both sides}\\ \quad \\
6\times 14=\cancel{6}\times \cfrac{3c}{\cancel{6}}\implies 84=3c\implies \cfrac{84}{3}=c\)

Answer 9

oh; I just figured this all out with my mom, sorry! I did that before I read this...
