THE DIFFERENCE OF TWO NUMBERS IS 4 AND THEIR SUM IS -7. WHAT IS THEIR PRODUCT. Who ever solved this correct will mark brainlist. 100%

33/4

Step-by-step explanation:

Let the first number be x, and the second number be y.

x - y = 4

x + y = -7

Solve for x in the first equation.

x - y = 4

x = 4 + y

Put x as (4 + y) in the second equation and solve for y.

4 + y + y = -7

4 + 2y = -7

2y = -7 - 4

2y = -11

y = -11/2

Put y as -11/2 in the first equation and solve for x.

x - y = 4

x - (-11/2) = 4

x + 11/2 = 4

x = 4 - 11/2

x = -3/2

Their product is:

-11/2 × -3/2

33/4

33/4

Step-by-step explanation:

We can use system of equations to find the missing numbers. Once we have the missing numbers, we can find the product. Let's use x and y for the missing numbers.

Equation 1

x-y=4

This equation comes from the difference of the 2 numbers being 4.

Equation 2

x+y=-7

This equation comes from the sum of the 2 numbers is -7.

We can use elimination to solve for y. We would subtract the 2 equations together so that x can cancel out.

-2y=11

y=-11/2

Now that we know y, we can substitute it into the equations above to find x.

x-(-11/2)=4

x+11/2=4

x=-3/2

With the x and y values, we can find the product.

(-3/2)*(-11/2)=33/4
