Question

What is the value of a in the equation 3 a plus b equals 54 when b equals 9?

Answer 1

Answer:-1/3b+18

Step-by-step explanation:

Let's solve for a.

3a+b=54

Step 1: Add -b to both sides.

3a+b+−b=54+−b

3a=−b+54

Step 2: Divide both sides by 3.

3a/3=  -b+54

               3

a= -1/3b+18
