Exercise 31 Page 41

Isolate C on one side through inverse arithmetic operations.

C=A(R/5+0.3)

Practice makes perfect

Let's solve for C by applying inverse operations until we have isolated C.

R=5(C/A-0.3)

.LHS /5.=.RHS /5.

R/5=C/A-0.3

LHS+0.3=RHS+0.3

R/5+0.3=C/A

LHS * A=RHS* A

A(R/5+0.3)=C

Rearrange equation

C=A(R/5+0.3)

Since C is isolated on one side, we have solved the given equation for C.
