Answer:
a=15
Step-by-step explanation:
[tex]5a-10b=45[/tex] is the given equation
The value of b is 3, replace the variable b by 3
[tex]5a-10b=45[/tex]
[tex]5a-10(3)=45[/tex]
[tex]5a-30=45[/tex]
To solve for 'a' , add 30 on both sides
[tex]5a=75[/tex]
Divide both sides by 5 to get rid of 5
a= 15
the value of a= 15
