What does a solution set mean?
Solution Sets for Equations The set containing all the solutions of an equation is called the solution set for that equation. If an equation has no solutions, we write ∅ for the solution set. ∅ means the null set (or empty set). Equation.
How do you write a solution set for an inequality?
It means, each and every value in the solution set will satisfy the inequality and no other value will satisfy the inequality.Example: Solve 2x + 3 ≤ 7, where x is a natural number. 2x + 3 ≤ 7. Subtracting 3 from both the sides,2x ≤ 4. Dividing both sides by 2,x ≤ 2. Example: x ≤ 4. Example 2: Solution:
What is a solution set on a graph?
The solution set is the line and the half-plane below and to the right of the line. Example 4 Graph x Solution First graph x = y.

How do you find common solutions?
Use elimination to solve for the common solution in the two equations: x + 3y = 4 and 2x + 5y = 5. x= –5, y= 3. Multiply each term in the first equation by –2 (you get –2x – 6y = –8) and then add the terms in the two equations together.
How do you solve inequalities by graphing?
How to Graph a Linear InequalityRearrange the equation so “y” is on the left and everything else on the right.Plot the “y=” line (make it a solid line for y≤ or y≥, and a dashed line for y)Shade above the line for a “greater than” (y> or y≥) or below the line for a “less than” (y
How do you solve an inequality step by step?
To solve an inequality use the following steps:Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions.Step 2 Simplify by combining like terms on each side of the inequality.Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other.
How do you solve inequalities with two variables?
To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality. If given a strict inequality, use a dashed line for the boundary. If given an inclusive inequality, use a solid line. Next, choose a test point not on the boundary.
