Two step equations

100

In our equation, when I do something to one side that isn't simplifying, do I have to do it to the other side too?

Keep the equation balanced

200

What should this answer be? (Not decimal)

x=14/4

x=7/2

300

Solve for x

3/2x=6

x=4

400

Solve for x

-1/4x=4

x=-16

500

How do I get rid of the fractions in this equation

1/4 x + 1/2 = 4

Multiply both sides by 4

Multi Step

100

Solve for x

2x+6=2(x+3)

Infinite solutions

200

Solve for x

4x+3=2(2x-3)

No solution

300

What should my first step be?

3x+4-13+2x=12

Combine like terms

400

Solve for x

4x=0

x=0

500

Simplify this

4(2x+3x+7)

20x+28

Inequalities

100

Name two integers x can be for this inequality?

x<4

Anything less than 4 but not 4

200

What i the difference between these in a line graph?

< <=

No equal sign means the circle is hollow

equal you fill the hole in

300

When you multiply or divide by a negative to both sides of the inequality then what happens to the inequality?

It flips

400

Solve the inequality

-4x+4<16

x>-3

500

Solve for x

1/4(-4x+16)<4

x>0

proportions

100

What is the first step to proportions?

3/4=x/6

Cross Multiply

3/4=x/6

(3)(6)=(4)(x)

200

Solve for x

(1+x)/4=1/2

x=1

300

How can you check if your answer is correct with proportions?

Plug it back in and see if you simplify them that they are equal

400

What does PEMDAS stand for and why do we use it?
