15=-3(2c+d) solve for c

The expression that represents c is -(5 + d)/2

The subject of formula is a way of representing  variables in terms of other variables

Given the expression

15=-3(2c+d)

Expand the expression in parenthesis

15 = -6c - 3d

Divide both sides by 3

5 = -2c - d

-2c = 5 + d

c = -(5 + d)/2

Hence the expression for c is -(5 + d)/2

c =

Step-by-step explanation:

Given

15 = - 3(2c + d) ( divide both sides by - 3 )

- 5 = 2c + d ( subtract d from both sides )

- 5 - d = 2c ( isolate c by dividing both sides by 2 )

= c
