Question

3a +5b =26 ; a + 5b =22

Answer 1

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 :)

Answer 2

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
