Let the first number be ( x ) and the second number be ( y ).
Given that four times the first number is decreased by three times the second number equals zero:
[ 4x - 3y = 0 ]
Also, the sum of the numbers is -7:
[ x + y = -7 ]
Now, solve the system of equations to find the values of ( x ) and ( y ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
