Multiple Choice

$$Solve\ the\ equation.\$$   $$g\ +\ 1\ =\ -4$$  

• g = -5

• g = -3

• g = 5

Multiple Choice

$$w\ -\ 2\ =\ -3$$  

• w = -5

• w = -1

• w = 1

Multiple Choice

$$\frac{r}{4}=\ -9$$  

• r = -36

• r = -5

• r = -13

Multiple Choice

$$2y\ =\ 2.8$$  

• y = 1.4

• y = 0.8

• y = 5.6

Multiple Choice

What is the correct step to do to solve?

$$6\ +\ x\ =\ 10$$  

• multiply by 6 on both sides

• subtract 6 on both sides

• add 6 on both sides

Multiple Choice

6 + x = 10

• x = 4

• x = 60

• x = 16

Multiple Choice

What is the correct step to solve?

$$m\ -\ 7\ =\ -9$$  

• add 7 to both sides

• add 9 to both sides

• subtract 7 on both sides

Multiple Choice

m - 7 = -9

• m = -2

• m = 0

• m - -16

Multiple Choice

What is the correct step to solve?

$$\frac{3}{4}x\ =\ 6$$  

• divide by 4, on both sides

• multiply by the reciprocal, $$\frac{4}{3}$$  , on both sides

• add $$\frac{3}{4}$$  to both sides

Multiple Choice

$$\frac{3}{4}x\ =\ 6$$  

• x = $$\frac{24}{3}=8$$  

• x = 1.5

• x = 6 $$\frac{3}{4}$$  

Multiple Choice

What would be the correct step to solve?

-7.5x = -7.5

• add 7.5 to both sides

• divide by -7.5 on both sides

• multiply by -7.5 on both sides

Multiple Choice

-7.5x = -7.5

• x = 0

• x = 1

• x = 56.25
