\[3(4c+16) = 4(2c+9)\]
OpenStudy (anonymous):
are you able to work that out now?
OpenStudy (emmamink):
12c + 12 = 2c +9 3=-10c -3/10
OpenStudy (emmamink):
-3/10 is the answer
OpenStudy (anonymous):
3 times 4c + 16 does not equal 12c + 12, try again

where did u get that from?
OpenStudy (anonymous):
@BPDlkeme234 that is not the math problem
OpenStudy (anonymous):
that means you can simply cross multiply to get 4* (2c + 9)
OpenStudy (emmamink):
i know BPDIkeme234 is crazy the answer is -3/10 don't listen to him
OpenStudy (emmamink):
So, help?!?!?!, that is the answer

No that is not the answer
OpenStudy (emmamink):
-3/10? yes it is
OpenStudy (anonymous):
right so, you end up with
3(4c+16) = 4(2c+9)
OpenStudy (anonymous):
multiplying this out you get what?
OpenStudy (anonymous):
3c+12=8c+36

oops -3 that is the answer. And symbolab.com is a great equation solver! so -3 is the answer
OpenStudy (anonymous):
I got 12c+48=8c + 36
OpenStudy (emmamink):
-3 people!!!!
OpenStudy (anonymous):
now, 12c - 8c = 36 -48
OpenStudy (anonymous):
i.e 4c = -12
