Answer 5

\[ \frac{(x+6)}{2}-1=\frac{(x+6)}{7} \] ?

Answer 6

Yes

Answer 7

multiply both sides by 14 (which is the common denominator of 2 and 7)
when you multiply the left side be sure to multiply 14 times *both* terms
can you do that ?

Answer 8

No I can't, I don't get it

Answer 9

to multiply (without simplifying) write 14 * next to each term
can you do that ?

Answer 10

Yes, one moment please

Answer 11

14(x+6)/2-1=(x-6)14/7

Answer 12

ok but you forgot the 1

Answer 13

I have to multiply 4 by one too?

Answer 14

yes,
if you have
1+1 =2
and you multiply both sides by 14
you do
14*1 + 14*1 = 2*14
which (if you work it out) is still true.
if you just did
14*1 + 1 = 2*14
it's gone horribly wrong.

Answer 15

Is it -8?

Answer 16

so you should have
14(x+6)/2-14*1=(x-6)14/7

Answer 17

\[ \frac{14(x+6)}{2} - 14 = \frac{14(x-6)}{7} \\
\frac{14}{2}(x+6) - 14 = \frac{14}{7}(x-6)
\]

now simplify 14/2
on the left side
and 14/7 on the right side
can you do that?

Answer 18

I already figured out the answer thanks
