Answer 1

To solve the equation 4a = 2b - 7, we need to isolate the variable a.

First, let's move the term 2b to the left side of the equation by subtracting 2b from both sides:

4a - 2b = -7

Next, let's simplify the left side of the equation by factoring out the common factor of 2:

2(2a - b) = -7

Now, divide both sides of the equation by 2 to solve for a:

(2a - b) = -7/2

2a - b = -7/2

Now, we have isolated the variable a. The equation is in standard form and cannot be simplified any further.
