Solving Inequalities by
Addition and Subtraction
Targeted TEKS
A.2(H) Write linear inequalities in two variables
given a table of values, a graph, and a verbal
description.
A.5(B) Solve linear inequalities in one variable,
including those for which the application of the
distributive property is necessary and for which
variables are included on both sides.
Mathematical Processes
A.1(E), A.1(F)
Solve by Adding
Solve c – 12 > 65. Graph and Check a solution.
Solve k – 4 < 10. Graph and Check a solution.
Solve by Subtracting
Solve the inequality x + 23 < 14. Graph and Check a
solution.
Solve the inequality m – 4  –8.
Variables on Each Side
Solve 12n – 4 ≤ 13n. Graph the solution and Check
a solution.
Solve 3p – 6 ≥ 4p. Graph the solution and check a
solution.
Define a variable for the given situation. Write an
inequality that represents the situation. Solve and
graph your solution set.
The sum of four times a number and 7 is at most triple
that number minus 5.
Define a variable for the given situation. Write an
inequality that represents the situation. Solve and
graph your solution set.
The difference of double a number and -9 is more
than four times that number plus 8.
Use an Inequality to Solve a Problem
ENTERTAINMENT Panya wants to buy season
passes to two theme parks. If one season pass
costs $54.99 and Panya has $100 to spend on both
passes, the second season pass must cost no
more than what amount? Write and solve an
inequality that represents this situation.
BREAKFAST Jeremiah is taking two of his friends
out for pancakes. If he spends $17.55 on their
meals and has $26 to spend in total, Jeremiah’s
pancakes must cost no more than what amount?
Write and solve an inequality that represents this
situation.
