Write an inequality that represents the phrase the sum of 1 and y is greater than or equal to 3. Check to see if y=1 is a solution

1 + y ≥ 3

y = 1 is not a solution

Step-by-step explanation:

Using the phrase: 'the sum of 1 and y', you can start with the expression:

1 + y

Next, 'greater than or equal to 3' can be using with the following sign:

≥ 3

Put them together and solve for y:

1 + y ≥ 3

Subtract 1 from each side: 1 + y - 1 ≥ 3 - 1 or y ≥ 2

Since y must be greater than or equal to the number 2, y = 1 is not a solution.
