x=1/3 and y=-2/3
Explanation:
3x-6y=5....eqn 1
2x+y=0... eqn2
rearrange eqn2
y=-2x... eqn3
put eqn3 into eqn1
3x-6(-2x)=5
3x+12x=5
15x=5
divide both sides by 15
x=5/15
x=1/3
substitute x in eqn2
2(1/3)+y=0
2/3 +y=0
y=-2/3
so,x=1/3 and y=-2/3
to check whether our answer is correct ☑️
insert the Value of x and y in eqn1
3x-6y=?
3(1/3)-6(-2/3)
1+4=5
so our solving is correct ☑️✅
