Answer 1

Answer:

Answer:

the right answer is:

(A) $2+(1)/(2)a$

Step-by-step explanation:

You take the equations that the exercise give you:

x + y = 4
x - y = a

Now you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:

x - y = a
-y = a - x

3. y = x - a

And now, you'll replace this third equation in the equation you didn't take (the first in this case).

x + y = 4
x + (x - a) = 4
x + x - a = 4

Add the x variables:

2x - a = 4
2x = 4 + a
x = (4 + a) / 2

That's the answer of the exercise, but you can represent this in this form:

x = (4 + a) / 2 ↔ $x = (4)/(2) + (1)/(2) a$

x = (4 + a) / 2 ↔ $x = 2+ (1)/(2) a$

By this reason, the right answer is $x = 2+ (1)/(2) a$ .
