The solution to the simultaneous equations 3x + 5y = 4, 4x + 3y = 5 is

A.

(1311,111)

B.

(1311,111)

C.

(1311,111)

D.

(1113,111)

E.

(13, 11)

Correct answer is B

3x + 5y = 4, 4x + 3y = 5

3x + 5y = 4 x 4

4x + 3y = 5 x 3

12x + 20y = 16.....(i)

12x + 9y = 15.......(ii)

subtract eqn.(ii) from eqn.(i)

11y = 1

y = 111

12x + 20 x 111 = 16

12x = 15611

x = 1311

= 1311,111
