two step algebra

33 = 4a - 7

• a=-10
• a=10
• a=4.5

6 - 3a = 21

• a= 9
• a= -9
• a= -5
• a= 5

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

26 = 5a + 1

• a= 5 ⁴∕₅
• a= no solution
• a= 0
• a= 5

20 = 2 - a

• a= 18
• a= -18
• a= -10
• a= 12

-5 - 6a = -59

• a= 11
• a= -6
• a= 9
• a= 2

3f - 12 = -3

• 3
• -3
• 11
• 12

To solve the equation
x + 5 = 8
 I would ....

• subtract 5 from x
• subtract 5 from both sides
• subtract 5 from one side and add 5 to the other
• add 5 to both sides

What is the inverse operation that must be done to both sides of the equation?
x - 17 = 17

• subtract 17 from both sides
• multiply both sides by 17
• add 17 to both sides
• divide both sides by 17

to solve 
2w + 8 =  28
You would first have to

• divide both sides by 2
• add 8 to both sides
• subtract 8 from both sides
