Question

The difference between twice a number, x, and a smaller number, y, is 3. The sum of twice the number and the smaller number is -3. Which equations represent this situation? -2x-3 and --2-3 o y=2x-3 and y=-x- Oy - 2x+3 and Y--2x-3 oy-2x+3 andy-

Answer 1

We were told that the difference between twice a number, x, and a smaller number, y, is 3. This is expressed as

2x - y = 3

Also, the sum of twice the number and the smaller number is -3. This is expreesed as

2x + y = - 3

Thus, the equations representing this situation are

2x - y = 3

2x + y = - 3
