Solving Multi-Step Equations

What is the goal when solving algebraic equations?

• to get the answer

• to isolate the variable (get the variable by itself)

• to get rid of the equal sign

• to divide

The inverse of addition is:

• addition

• multiplication

• subtraction

• division

The inverse of multiplication:

• addition

• subtraction

• multiplication

• division

 $21=3+4n+5n$  

• 9

•  $-7$  

• 6

• 2

 $96=6\left(k+8\right)$  

•  $12$  

•  $8$  

•  $-4$  

•  $9$  

 $97=-3\left(6n-5\right)-8$  

•  $-10$  

•  $16$  

•  $-5$  

•  $-2$  

4 = 2(x + 3)

• 1/2
• 7/2
• -1
• 5

5x - 4 + 2x = 3

• 1

• 2

• 3

• 4

Solve for v.

• 60
• -3
• 15
• 3

Which step cannot be performed first when solving the equation
5 - 2(x - 7) = x + 1 + 3x

• Distributing -2 to (x - 7)
• Combining x and 3x
• Subtracting 1 from both sides
• 5 - 2
