Substitution in math typically involves replacing a variable with an equivalent expression to simplify an equation or solve for a variable. For example, if you have ( y = 2x + 3 ) and want to substitute ( y ) in another equation, you would replace ( y ) with ( 2x + 3 ). This process allows you to work with a single variable, making it easier to solve equations or systems of equations. Always ensure to perform the same operations on both sides of the equation to maintain equality.
