-3=x+5

• add 3 to both sides
• subtract 5 from both sides
• add 5 to both sides
• subtract -5 from both sides

What would be the best first step to solving the equation?

• multiply both sides by 3
• multiply both sides by 4
• divide both sides by 3
• divide both sides by 4

What would be the best first step to solving the equation?
-18=m+12

• add 18 to both sides
• subtract 18 from both sides

• 9
• 7
• 6
• 8

In an equation or inequality, you want to get the variable...

• on one side
• to disappear
• by itself

Solve the equation: 
x + 7 = 12

• x = 5
• x = 19
• x = 4
• x = 84

Solve the equation:
4p = 16

• p = 12
• p = 64
• p = 3
• p = 4

Solve the equation:
x/3 = 4

• x = 12
• x = 1
• x = 16
• x = 3

Which of the following are basic rules used for solving algebraic equations?

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign

• Negative signs can be ignored

• Always start on the left side, regardless of where the variable is

• Always do the opposite operation

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.
