Answer:
[tex]a=\frac{3}{2}b[/tex]
Step-by-step explanation:
The given expression is [tex]7a-2b=5a+b[/tex]
To solve for [tex]a[/tex], we add 2b to both sides to get
[tex]7a=5a+b+2b[/tex]
We now add -5a to both sides:
[tex]7a-5a=b+2b[/tex]
We simplify both sides to get:
[tex]2a=3b[/tex]
We now divide both sides by 2 to get:
[tex]a=\frac{3}{2}b[/tex]
