Me on all 7 if you can only solve some don't hesitate & say those

1) let say a + b = -16
than 3times larger equal smaller can be represent by 3a = b.
now sub 3a into the b of the equation and simplify you will get 4a = -16 where a = -4 and a is the larger nymber since b will =-12 which is smaller than a
