Question

c(a+b)-d=f
solve for b
then solve for d

Answer 1

First solve the parenthesis then you have
ca +cb-d=f
then you want to isolate b, move what does no contain b to the right as follows:
cb = f - ca + d (change the signs when you move it)

Answer 2

Then to isolate the b you devide by c, you have
b= f - ca + d
---------
c

Answer 3

Therefore you have
b = f/c -a +d/c

Answer 4

To solve for d is much easier, since the d is by itself

Answer 5

very helpful both strategies thanks !!!!!!!!!!!!!!!!!

Answer 6

is d=c(a+b)-f
