PLEASE HELP ASAP THIS IS AN ASSIGNMENT. JSUT WRITE A WORD PROBLEM

Define two different variables for your problems.
Write two algebra equations or inequalities using the information given in your word problem. Both of your equations or inequalities must contain both variables
Using your two equations or inequalities, solve your problem twice for both variables. Once using the addition/elimination method and a second time using the substitution method showing all algebra work with both methods.
Check your solutions with both of your equations or inequalities showing all algebra work for both checks.
Explain why it is important to always check all solutions with both equations for a system of equations problem.

Answer:

26 = 21 + 5

Explanation:

ven without solving them, you know that the quantity on the left-hand side of the equals sign has the same value as the quantity on the right-hand side of the equals sign.

Inequalities are different. In an inequality, one side of the inequality can be larger or smaller than the quantity on the other side. The math symbols <, ≤, >, and ≥ provide information about the relative sizes of the two expressions.

The important thing about inequalities is that there are multiple possible solutions. For example, the inequality “50 ≥ the number of stars on any United States flag” is a true statement for every American flag ever flown—no flag has had over 50 stars. It holds true for the flag as it was designed in 1777 (13 stars, 50 ≥ 13), as it looked in 1850 (30 stars, 50 ≥ 30), and how we see it today (50 stars, 50 ≥ 50).

Note that the inequality x > y can also be written as y < x. The sides of any inequality can be flipped as long as the inequality symbol between them is also reversed.

y = 3x + b

5t = 2(t + 3)

x < y

“x is less than y”

3 < 15

x ≤ y

“x is less than or equal to y”

number of people present in class ≤ number of people enrolled in class

x > y

“x is greater than y”

number of countries in the world > number of continents in the world

x ≥ y

“x is greater than or equal to y”

50 ≥ the number of stars on any United States flag
