Solve One Step Equations Given The Variable

In the equation
x + 7 = 12
7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation? 

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.
  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

Solve the equation
3x = 27. 

• x = 24

• x = 81

• x = 9

5 less than a number is 15.

• x - 5 = 15

• 5 - x = 15

• 15 - x = 5

Which equation has w = 8 as the solution?

• 8w= 64

• 16w = 240

• 16 - w = 9

• 4 + w = 10

-16+ x= -15

• 2

• 0

• -1

• 1

To solve the equation:

4p = 16

what needs to be done to both sides to isolate the variable?

• Add 4

• Subtract 4

• Multiply by 4

• Divide by 4

Mathematically, what is the 10 doing to the x?

10x = 90

• Adding 10

• Subtracting 10

• Multiplying 10

• Dividing 10

Solve the equation:
-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

Solve the following equation
1 + a = 15

• 14

• 16

• 12

• - 16
