solving two step equations

What you do on one side, you must do to the other.

what you do to one side, you must do to the other.

Multiple Choice

To solve this equation for w, what is the first step?

3w—6=9

• add 6 to both sides.

• subtract 6 from both sides.

• subtract 9 on both sides.

• divide by 3 on both sides.

Multiple Choice

Now that we added 6 to both sides, what is the next step?

3w=15

• multiply 3 on both sides.

• divide by 3 on both sides.

• subtract 15 on both sides.

• nothing, it's solved already.

Multiple Choice

Once we divide by 3 on both sides, what does "w" equal?

3w=15

• w= 5

• w= 3

• w= 45

• I don't know!

Open Ended

How do we double check that we solved for "w" correctly?

3w - 6 = 9 (w = 3)

Multiple Choice

To solve this equation for y, what is the first step?

4y+(6+4)=30

• solve inside the parentheses

• 6 - 4

• divide 4 on both sides

• multiply 4 on both sides.

Multiple Choice

Now that we added the numbers in the parentheses, what is the second step?

4y+10=30

• subtract 30 on both sides

• add 10 on both sides

• subtract 10 on both sides

• multiply 4 on both sides.

Multiple Choice

Now that we subtracted 10 on both sides, what is the third step?

4y = 20

• subtract 20 on both sides

• add 10 on both sides

• divide by 4 on both sides

• multiply 4 on both sides.

Multiple Choice

Now that we divided by 4 on both sides, what is the value of y?

4y = 20

• 20

• 5

• 4

• 80

Open Ended

How do we double check that we solved for "y" correctly?

4y + (6+4) = 30 (y=5)

Multiple Choice

To solve this equation for g, what is the first step?

g ÷ 2 + 8 = 11

• multiply 2 on both sides

• divide by 2 on both sides

• add 8 to both sides

• subtract 8 on both sides

Multiple Choice

Now that you subtracted 8 on both sides, what is the second step?

g ÷ 2 = 3

• multiply 2 on both sides

• divide by 2 on both sides

• add 3 to both sides

• subtract 3 on both sides

Multiple Choice

Now that you multiplied by 2 on both sides, what is the value of g?

g ÷ 2 = 3

• 6

• 5

• 8

• 12

Open Ended

How do we double check that the value for "g" is correct?

g ÷ 2 + 8 = 11 (g = 6)
