Solve for a
7a - 2b = 5a + b
a = 2b
a = 3b
a = 3/2b
a=2/3b​

Answer 1

Isolate the variable by dividing each side by factors that don't contain the variable.

a = 3b/2

Explanation:

Answer 2

Therefore solution for a is

`a=(3b)/(2)`

Explanation:

Given:

7a - 2b = 5a + b

To Find:

a = ?

Solution:

7a - 2b = 5a + b .................Given

First take all the 'a' terms to the left hand side and 'b' terms to the right-hand side of the equation,

∴
`7a-5a=2b+b\\\\2a=3b`

Now dividing by 2 on both the side we get

∴
`(2a)/(2) =(3b)/(2) \\\\\therefore a=(3b)/(2)`

Therefore solution for a is

`a=(3b)/(2)`
