Answer:

The first number is -6. The second number is -4.

Step-by-step explanation:

Let the second number be x.

"one number is 2 less than a second number"

Second number: x

First number: x - 2

"twice the second number is 22 more than 5 times the first"

2x = 5(x - 2) + 22

Distribute on the right side.

2x = 5x - 10 + 22

Subtract 5x from both sides. Combine like terms on the right side.

-3x = 12

Divide both sides by -3.

x = -4

x - 2 = -4 - 2 = -6

The first number is -6. The second number is -4.
