please answer fast ​

Answer 1

Answer:

This is the correct answer of your question .

Answer 2

Step-by-step explanation:

4a -2b= -15

2a-b = -15/2

a-b/2 = -15/4 ---> equation 1

a^2-b^2 = 1

here a = a and b= b/2

(a+b/2)( a-b/2) = 1

a+b/2 = 1 ÷ 15/4

a+b/2 = 4/15---> equation 2

add equation 1 and 2

a-b/2 = -15/4

a+b/2 = 4/15_________

2a = -15/4 +4/15

2a = -209/60

a -209/120

now you can find b value easily and eventually a+b

hope this answer is correct and helps you
