• 80

• 16

• 5

• 24

What is the solution to x/4 = 20?

Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations

• math

• variable

• PEMDAS

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides

• Add the 2a and a 

• Distribute 4 to a and -5

• Distribute -4 to a and -5

-15 = 5a +12- 2a + 6

• -11

• -3

• 10

• 7

4(a + 3) = -32

• -11

• -44

• -20

• -8

Solve:
3(3x - 6) = 18

• x = 4

• x = -4

• no solution

• infinite solutions

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

What is the first step to complete when solving this equation?
10 - 3x = 4

• Subtract 10

• Add 10

• Add 3

• Divide by -3

Inverse operations can also be called:

• Combine like terms

• Opposite operations

• Two Step Equations

• Distributing
