Question

by eliminating method of 3x-5y=1,5x+2y=19.​

Answer 1

Elimination Method

3x - 5y = 1 ----------->(1)

5x + 2y = 19 -------->(2)

multiplying from 5 in equation (1) and multiplying with 3 in equation (2)

15x - 25y = 5

15x + 6y = 57

-___-____-____

-31y = -52

y = 52/31

now, putting y = 52/31 in equation (1)

3x - 5 (52/31) = 1

3x - (260/31) = 1

3x = 1 + 260/31

3x = 291/31

x = 97/31

x = 97/31

y = 52/31
