100 points!!!!Solve for a7a - 2b = 5a + ba = 2ba = 3ba = 3/2b a=2/3b​

Answer 1

Answer:

Therefore solution for a is

$a=\frac{3b}{2}$

Step-by-step 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

∴ $\frac{2a}{2} =\frac{3b}{2} \\\\\therefore a=\frac{3b}{2}$

Therefore solution for a is

$a=\frac{3b}{2}$
