Question

2. Solve the following simultaneous equations.
(1) 3a + 5b = 26; a + 5b = 22 (2)​

Answer 1

Step-by-step explanation:

3a + 5b = 26

a + 5b = 22

2a= 4

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.
