Question

5x – 2y = 1; 3x + 5y = 13​

Answer 1

Answer:

by substitution method

5x-2y=1. (1)

3x+5y=13. (2)

x=1+2y/5. (3)

put value of x in eq 2 we get

3×(1+2y/5)+5y=13

3+6y/5+5y=13

3+6y+25y/5=13

3+31y=13×5

31y=65-3

y=62/31

y=2

put the value of y in eq 3 we get

x=1+2y/5

x=1+2×2/5

x=1+4/5

x=5/5

x=1
