YES, I have my notebook out, I mean, I want to learn and be successful.

Uh...No, and I know it means a bad grade, I have accepted my fate.

Solving Multi-Step Equations

Objective: Solve equations involving multiple steps to isolate the variable.

with Distribution and Combining Like Terms

Multiple Choice

See if you remember.

Distribute: -9(x - 4)

-9x + 36

-9x - 36

9x + 36

9x - 36

DISTRIBUTION

EXAMPLES

4(x - 7) = 4x - 28

-3(2x - 4y) =

-(5x - 3) =

EXAMPLES with Distribution

4(n - 2) = 28

32 = -4(x - 3)

Math Response

Solve: -21 = 3(x - 5)

Type answer here

Deg^°

Rad

Like Terms: terms that have the SAME variable(s)

Examples: 4x and 17x

Vocabulary

Combine Like Terms: take multiple like terms and make them one. Another word used is SIMPLIFY.

EXAMPLE: 4x + 8 - 9x + 10x - 12

Math Response

Simplify: 13 - 5x + 4 + 3x - 7

Type answer here

Deg^°

Rad

EXAMPLES with Like Terms

-8e + 7 + 3e = -13

1 - 3p − 5 = −16

Math Response

Solve: −5x + 13 + 7x = 1

Type answer here

Deg^°

Rad

3r + 4(r - 2) = 13

EXAMPLE

with Distribution and Like Terms

1) Distribute if you can

2) Combine Like Terms if you can

3) Add or Subtract on both sides if you need to

4) Multiply or Divide on both sides if you need to

Math Response

Solve: 2(x + 7) - 7 = 5

Type answer here

Deg^°

Rad

EXAMPLE

48 = 6(3x - 1) + 9x

this video covers all the kinds of examples we have done in this lesson

Math Response

Solve: 3(2x + 9) - 4x = 29

Type answer here

Deg^°

Rad
