Algebraic solutions and number line
An algebraic solution is a specific number that makes a mathematical equation or inequality true. For example, consider the inequality:
2x + 1 > 5
This inequality tells us that for any value of x that is greater than -3, the expression 2x + 1 must be greater than 5. This means that the only solution to the inequality is x > -1.
Number line is a visual representation of the real numbers that uses points to mark different values. The number line is typically divided into equal intervals, each representing a constant difference. The points on the number line correspond to the values of the real numbers.
To find the algebraic solution to an inequality, we can isolate the variable on one side of the inequality sign. This means that we perform operations to both sides of the inequality, ensuring that all the variables cancel out and we are left with a single expression that is equal to the original inequality.
The number line can be used to visualize the solutions to inequalities. We can plot the values of the variable on the number line and then determine which values make the inequality true.
Examples
x > 11
x ≤ 4
x ≥ 2
