Question

Help solve (3-a)(b+c) 9/x-5/x 52;x/8=6

Answer 1

are there three questions or ... ? \[\LARGE (3-a)(b+c)=3b+3c-ab-ac\]

\[\huge \frac{a}{x}\pm \frac bx=\frac{a+b}{x}\]

and you have..

\[\LARGE \frac9x-\frac5x=?\]
can you do it ??

Answer 2

yeh the third one is 52;x/8=6

Answer 3

... sorry I made a mistake it's..\[\huge \frac{a}{x}\pm\frac{b}{x}=\frac{a\pm b}{x}\]

Answer 4

Thanks so much.....would that be 4/x???

Answer 5

\[\LARGE \frac{52x}{8}=6\] ....

use cross multiply and you'll get

\[\LARGE 52x=6\cdot 8\]

\[\LARGE x=\frac{6\cdot 8}{52}\]

I'll leave you to finish it...

Answer 6

yes option b is 4/x ... well done ;)

Answer 7

thanks again

Answer 8

Glad to help ;) ... You're welcome :)

Answer 9

x=48/52 would that be right

Answer 10

now simplify it ... 48:2 and 52:2 you'll get:

\[\LARGE x=\frac{48}{52}\Longrightarrow x=\frac{24}{26}\] simplify by 2 again... (or other numbers if it's necessary ... till there's no more to simplify ;) ) can you do it ?

Answer 11

x=12/13

Answer 12

that's correct ... well done ! ;)
