Question

Write an inequality that represents the phrase. Then show the solution to the inequality.

The sum of 1 and x is less than 5

Answer 1

The original inequality is 1+x < 5

That inequality solves to x < 4

================================================

Step-by-step explanation:

The term "sum" means "result of addition". For example, the sum of 3 and 7 is 3+7 = 10.

In this problem, the sum of 1 and x is 1+x. We don't know what x is, so we can't combine it with the 1. We leave it as is.

The expression 1+x is less than 5, meaning we write 1+x < 5

To solve this, we subtract 1 from both sides

1+x < 5

1+x-1 < 5-5

x < 4 is what happens when you isolate x.

This describes any number smaller than 4.

Answer 2

Inequality that represents the phrase:
1 + x < 5

To solve:
Subtract 1 from both sides.
Your solution to the inequality is x<4
