Distribute the 7.
TheSmartOne (thesmartone):
You should use this property \[a(b+c)=ab+ac\]
TheSmartOne (thesmartone):
So what do you get so far? @qdbug
OpenStudy (anonymous):
Well i get easily confused by this stuff, im in regular math but my teacher is extemely confusing so could i rewrite as 71+76m?
TheSmartOne (thesmartone):
No it would be \[7(1+6m)=7\times1 + 7 \times 6m=7+42m\]

you have to multiple not just put that number in front of those variables/numbers
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
7(1+6m)=343
(expand the 7)
42m+7=343
now can you solve 42m+7=343?
TheSmartOne (thesmartone):
Just subtract the 7 and divide by 42.. and you have gotten m
OpenStudy (anonymous):
yes
