Review of Solving One Step Algebra

The objective when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• Combine Like Terms.

19  + a  =  -50

• a = -950
• a =  -69
• a = -31
• a = -50/19

What is the inverse operation needed to solve for p?
765 = p - 254

• subtraction
• addition
• multiplication
• division

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.

What equation matches this situation?
Robyn had some video games then bought 4 more.  Now she has a total of 10 games.

• v - 4 = 10
• v + 4 = 10
• 10 - 4 = v
• Answer not Given

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

Solve the equation:
x - 5.5 = 10.5

• x = 16
• x = -15
• x = 5
• x = -5
