To find the value of an algebraic expression, numbers must be substituted for the variables. In algebraic expressions, numbers substituted for the value of a variable are called the replacement set. The answers that are generated when the replacement set is substituted for the variables, are called the solution set.
Replacement Set
x = {4}
Expression
2x + 6
2(4) + 6
Solution Set
{14}
Find the solution set for the following expressions with the given replacement sets. Enter multiple answers in increasing order, separated by commas (such as -3,4) in the solution set column.
Replacement Set
x = {4}
a = {-2}; b = {1,3}
Expression
4x + 4
2a - 3b
Solution Set
