The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.
It means to substitute a number values into an expression.
to evaluate an algebraci expression replace ech variable with a number. then follow the order of operations to dimply the expressio. Hope that helped :)
Substitute the number in place of the variable, and see whether the inequality is then a true statement.
Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number
It depends on the value of x. The x is a variable. To evaluate an expression, you need to have a value (number) to replace the x.
