Question

Write the equations: The difference of two numbers is -10 and the sum is -4.

Answer 1

what is x and y

Answer 2

is this correct?

Answer 3

Let's assume the first number is x and the second number is y.

According to the given information, we can write two equations:

1) The difference of two numbers is -10: x - y = -10
2) The sum of two numbers is -4: x + y = -4

Answer 4

To find the values of x and y, we can solve the system of equations.

From equation 1: x - y = -10
From equation 2: x + y = -4

We can add these two equations together to eliminate y:
(x - y) + (x + y) = -10 + (-4)
2x = -14
x = -7

Plugging this value of x back into equation 2 to find y:
-7 + y = -4
y = -4 + 7
y = 3

Therefore, x = -7 and y = 3.

Answer 5

Yes, the values x = -7 and y = 3 are correct.
