1-3over4 (c+2)=-5

OpenStudy (anonymous):

need help n explain it to me

OpenStudy (anonymous):

\[1-\frac{3}{4}(c+2)=-5\] is this it? and assuming you need to solve for c

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

the goal here is to get c all by itself on one side however, if you want to add, subtract, multiply,divide anything to one side to get rid of something, the same must be done to the other side so starting with what's given we want to get rid of the 1 on the left side, this can be done by subtracting one to both sides \[1- \frac{3}{4}(c+2)-1=-5-1\] \[- \frac{3}{4}(c+2)-1=-6\]

OpenStudy (anonymous):

can you solve it from here?

OpenStudy (anonymous):

umm cant :(

OpenStudy (anonymous):

ok well we want to get rid of the -3/4 what can we multiply to that to make it equal to 1?

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

do u +2 to both sides

OpenStudy (anonymous):

is it equal 6 the answer

OpenStudy (anonymous):

im going to assume you did all the steps yourself, yes 6 is the answer

OpenStudy (anonymous):

actually because you're solving for c the answer is c=6

OpenStudy (anonymous):

ok thxs can u jux put that in answer n show all the work please

OpenStudy (anonymous):

can u double check this for me

OpenStudy (anonymous):

k one sec

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

k one sec \[1- \frac{3}{4}(c+2)=-5\] \[1- \frac{3}{4}(c+2)-1=-5-1\] \[- \frac{3}{4}(c+2)=-6\] \[(-\frac{4}{3})(- \frac{3}{4})(c+2)=-6(-\frac{4}{3})\] kinda combined multiply by -1, multiplying by 4, and dividing by 3 together \[c+2=8\] \[c+2-2=8-2\] \[c=6\]

OpenStudy (anonymous):

remember, anything you do to one side, you always need to do it to the other, otherwise it wouldnt be a balanced equation anymore
