Question -
Answer -
Solution:
Given equations are
2x + y = 23 …(i)
4x – y = 19 …(ii)
On adding bothequations, we get
6x = 42
So, x = 7
Put the value of x inEq. (i), we get
2(7) + y = 23
y = 23 – 14
so, y = 9
Hence 5y – 2x = 5(9) –2(7) = 45 – 14 = 31
y/x – 2 = 9/7 -2 =-5/7
Hence, the values of(5y – 2x) and y/x – 2 are 31 and -5/7 respectively.
