Answer:
The value of a is 15
Step-by-step explanation:
Given the equation
[tex]5a-10b=45[/tex]
we have to find the value of a when b is 3
[tex]5a-10b=45[/tex]
Substitute b=3, we get
[tex]5a-10(3)=45[/tex]
[tex]5a-30=45[/tex]
[tex]5a=45+30=75[/tex]
[tex]a=\frac{75}{5}=15[/tex]
Hence, the value of a is 15
