Answer 1

answer

if u want to find its square that be 25and9

Answer 2

Answer:

a = 11/7

b = 1/7

Step-by-step explanation:

3a + 2b = 5....(i)

2a - b = 3....(ii)

=> 2a = 3 + b

=> 2a - 3 = b

=> b = 2a - 3

Now put the value of b in equation (i).

=

3a + 2b = 5

=> 3a + 2(2a - 3) = 5

=> 3a + 4a - 6 = 5

=> 7a = 5+6

=> 7a = 11

=> a = 11/7

Now put the value of a in equation (i).

2a - b = 3

=> 2(11/7) - b = 3

=> 22/7 - b = 3

=> 22/7 = 3 + b

=> 22/7 - 3 = b

=> 22-(3×7)/7 = b

=> 22-21/7 = b

=> 1/7 = b

Hence a = 11/7 and b = 1/7

hope it helps.
