Question

3x-y=20
what is x and y

Answer 1

You can take x= 0 &y= -20 or you can also take x= 1/3 & y= -19.

Then you can verify your answer by putting these values in the equation:

3x-y=20

=>3×0-(-20)=20

=>0-(-20)=20

=>0+20=20

=>20=20

=>LHS=RHS

THEREFORE x= 0 &y= -20

OR

3x-y=20

=>3×(1/3)-(-19)=20

=>1-(-19)=20

=>1+19=20

=>20=20

=>LHS=RHS

THEREFORE x= 1/3 & y= -19
