Question

Solve for x and y 2(x+3) +3(y-1) =8, 3(x-2) +2(y+2) =3 and two question 10(x+2y) =3, 10(2x-y) =1

Answer 1

Your answer.......

1.)2(x+3)+3(y-1)=8

=2(4+3)+3(5-1)=8

=2+7+3+4=8

=9+7=8

=16=8 It is not true....

2.)3(x-2) +2(y+2) =3

=3(4-2)+2(5+2)=3

=3+2+2+7=3

=6+9=3

=15=3 It is not true....

3.)10(x+2y) =3

=10(4+2×5)=3

=10+30=3

=40=3 It is not true....

4.)10(2x-y) =1

=10(2×4-5)=1

=10+3=1

=7=1 It is not true....
