Equations Classwork Practice 801

The goal of solving a one, two, or multi-step equations is to:

• Find the constant

• Find the coefficient

• Find the value of the variable

• Be confused

We solve equations using

• fractions

• the distributive property

• inverse operations

• factors

Inverse means

• same

• opposite

• equal

A number with no variable attached is called a  _____.

• coefficient
• constant
• variable
• term

Solve the equation:
7x - 4 = 3 + 8x

• x = 7
• x = -7
• x = 2/7
• x = 11

A letter that represents a number is called a _____.

• variable
• coefficient
• constant
• term

What is the first step you should take to solve this problem?

-3(x - 2) = -8 +9b

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2

• add 2 to both sides

Solve:
5y + 34 = -2(-7y+1)

• y = -4
• y = 9
• y = 4
• y = 36/19
