Answer:
b = (d-c)/a
Step-by-step explanation:
ab + c = d
We want to solve for b, so we need to get b alone
Subtract c from each side
ab+c-c = d-c
ab = (d-c)
Divide each side by a
ab/a = (d-c)/a
b = (d-c)/a
Answer:
3/2
Step-by-step explanation:
It is proportional because it is 6/4 simplified.
Y/x=k
when y=9, then x= -3
9/-3=-3
⇒ k= -3
