Salutations!

3a+b = 54

Replace b as 9

3a+9=54

3a=54-9

3a=45

a= 45/3

a=15

Thus, your answer is 15

Hope I helped (:

Have a great day!

How do u do this problem: W/6+5/8=-1 3/8 <br> I got this answer: -1 53/64
Kobotan [32]
We have question
\frac{W}{6}+ \frac{5}{8} =-1 \frac{3}{8}    
\frac{W}{6} + \frac{5}{8} =- \frac{11}{8}  <span> /*8      (multiply both sides by 8)</span>
\frac{W8}{6} + \frac{5}{1} =- \frac{11}{1}  /*6      (multiply both sides by 6)
8W+5*6=-11*6      /-30 both sides
8W=-66-30
8W=-96
W=-12
