Answer 1

Answer:

a = 2x - b

Step-by-step explanation:

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

Use the reciprocal of 1/2 to get rid of the fraction by multiplying both sides of the equation by 2/1:

$(\frac{2}{1})x = \frac{a + b}{2} (\frac{2}{1})$

2x = a + b

finally, subtract b from both sides of the equation to isolate a:

2x - b = a + b - b

2x - b = a
