Basic Solving Algebra

In math class, the word variable refers to:

• a term that contains a letter

• a term that contains no letters

• a negative integer

• a positive integer

What is the first step in solving the following equation?
3x - 5 = 20

• multiply both sides by 5

• add 5 to both sides

• divide both sides by 5

• subtract both sides by 5

2 (n + 5) = -2 The first step in solving the following equation is ____________

• add five to both sides

• distribute 2 to all terms in the parenthesis

• add 2

-9x + 1 = -80

• -9

• 9

• 6

-9x-13= -103

• 15

• 10

• 12

144 = -12(x+ 5)

• -7

• -17

• 14

Distribute: -3\left(x-5\right)

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

Solve  3x - 7 = 32

• 13

• -13

• 12

• -12

-11 + 3(b + 5) = 7

• b = 1

• b= -1

• b = 3

• b = -3
