Solving Equations & Inequalities

An equation is a mathematical statement that asserts the equality of two expressions, typically containing variables.

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

Add 37 to both sides: m = 124 + 37 = 161.

Subtract 13 from both sides: y = 24 - 13 = 11.

Subtract 12.2 from both sides: x = 28 - 12.2 = 15.8.

It means that the value of f must be at least 20 for the inequality to hold true.

You perform inverse operations to both sides of the equation to get the variable by itself.

Add 8 to both sides: r = 15 + 8 = 23.

To verify that the solution satisfies the original equation.

To find all values of the variable that make the inequality true.
