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]
