Here is ur ans___________:)
3a+5b=26
a+5b=22
_________
on subtraction signs will change
3a+5b=26
-a-5b=-22
__________
2a=4
a=4/2
a=2
now substituting a=2 in equation 1
3×2+5b=26
6+5b=26
5b=26-6=20
b=20/5
b=4
so a=2 and b=4
hope it helps so pls mark as brainleist :)

Step-by-step explanation:
Solution :-
3a + 5b = 26 ....................(1)
a + 5b = 22 ......................(2)
Subtracting (2) from (1), we get
3a + 5b = 26
a + 5b = 22
- - -
____________
2a = 4
____________
⇒ 2a = 4
⇒ a = 4/2
⇒ a = 2
Substituting the value of a = 2 in (2), we get.
a + 5b = 22
⇒ 2 + 5b = 22
⇒ 5b = 22 - 2
⇒ 5b = 20
⇒ b = 20/5
⇒ b = 4
