Question

solve the
Following simultaneous equations
34+ 5b = 26, a tsb = 22​

Answer 1

Answer: pls mark me as brainliest

Step-by-step explanation:

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

So. the value of a is 2 and the value of b is 4
