Algebraic equation - the basics

A numerical statement in which two expressions are equal to each other is called a / an

• expression

• equation

• inverse operation

• term

3h +8 is an example of a / an

• algebraic expression

• algebraic equation

• term

• variable

In the expression 4t + 7, the t is a / an

• constant

• coefficient

• variable

Solve for y:

3y + 8 = 29

• y = -7

• y = 18

• y = 7

• y = 21

Write an equation for the following word problem:

32 less a number is equal to 15.

• 32 - n = 15

• n - 32 = 15

• n = 32-15

• 32 +15 = n
