Question

Solve for c.
a=11+4b−4c

Answer 1

Ok so first we subtract 11 on each side so we get a-11=4b-4c then we do-4b on each side to gets a-11-4b=-4c finally divide -4 to each side to get a-11-4b/-4=c

Answer 2

Consider the expression

$a=11+4b-4c.$

First, separate variables: left 4c in the right side and all rest write in the left side:

$a-11-4b=-4c.$

Then multiply by -1:

$-a+11+4b=4c.$

At last, divide by 4:

$c=\dfrac{-a+11+4b}{4}.$
