Find two integers whose difference is -6. ( There are many!)
olga nikolaevna [1]

Step-by-step explanation:

There are infinitely many such integers.

x - y = -6            <em>add y to both sides</em>

x = -6 + y → x = y - 6

1. Choose any y value.

2. Substitute for the equation.

3. Calculate the value of x.

Examples:

for y = 0 → x = 0 - 6 = -6

check: -6 - 0 = -6

for y = 10 → x = 10 - 6 = 4

check: 4 - 10 = -6

for y = -9 → x = -9 - 6 = -15

check: -15 - (-9) = -15 + 9 = -6
