Question

1. Solve :
3a + 5b = 26; a + 5b = 22 plz Full Explanation​

Answer 1

Step-by-step explanation:

3a+5b=26----------(1)

a+5b=22------------(2)

(-) (-). (-)

----------------------

2a=4

a=2

substitute value a=2 in equation (2)

2+5b=22

5b=22-2

5b=20

b=20/5,b=4

Therefore a=2,b=4

Answer 2

Answer:

3a + 5b = 26; .....(I)

a + 5b = 22 .....(II)

Subtracting (II) from (I)

2a = 4

⇒ a = 2

Putting the value of a = 2 in (II)

5b = 22 - 2 = 20

⇒b = 20/5

=4

Thus, a = 2 and b = 4.
