Question

5x - 2y = 1,
2x - y = 0.

Answer 1

Consider the equations as:-

$5x-2y=1->(i)\\2x-y=0->(ii)$

Now, eqn (ii) x 2, we get

$4x-2y=0->(iii)$

solving eqns. (I) and (iii) by elemination method(i.e eqn (i) - eqn (iii))

$5x-2y = 1\\-4x+2y=0\\-------\\x = 1$

putting, value of $x$ as 1 in eqn (ii), we get

$y=2$

Hence, you get $x$ as 1  and $y$ as 2.
