Here's your answer
Equation : 2x-5y=10
(1) x=0 and y=2
= 2(0)-5(2)=10
= 0-10=10 ;So Its not the Solution
(2) x=0, y=(-2)
= 2(0)-5(-2)=10
=10=10. ; Hence its the solution
(3) x=5 and y =0
= 2(5)-5(0)=10
10=10....Hence its also a solution..
(4) 2(2√3)-5(-√3)=10
=4√3+5√3=10
=9√3= 10.....Not a solution
(5 )x=1/2 and y=2
=1-10=10
9=10....Not a solution
Hope it helps!!
