Question

The sum of two numbers is -3
. Two times the first number minus the second number is 12
. Find the two numbers.

The first number is 4
, and the second number is -7
.

The first number is 3
, and the second number is -6
.

The first number is -3
and the second number is 6
.

The first number is 2
, and the second number is -5
.

Answer 1

Let the numbers be x (first) and y (second). From
x + y = -3
2x - y = 12

Add the equations: 3x = 9, so x = 3. Then y = -3 - x = -3 - 3 = -6.

So the first number is 3 and the second number is -6 (the second choice).
