Question

4a=2b-7 solve for b anyone know how to do this?

Answer 1

Answer:

$b=2a +\frac{7}{2}$

Step-by-step explanation:

$4a=2b-7$ solve for b

To solve for b, we need to get b alone

We need to remove -7 to isolate 2b

$4a+7=2b-7+7$

$4a+7= 2b$

To get 'b' alone we divide both sides by 2

$\frac{4a}{2} +\frac{7}{2} =b$

$2a +\frac{7}{2} =b$

$b=2a +\frac{7}{2}$

Answer 2

I know how to solve it but the value of 'a' is required for solution.
