Assignment #6

What is the solution to this equation?

• one solution
• no solution
• infinite solutions
• none of these

3(x-8)=3x-24

• No Solution

• x=3

• Infinite Solutions

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

2x + 3(5x - 7) = 47

• 1
• 2
• 3
• 4

-8(-8x - 6) = -6x - 22

• 2/5
• -1
• 8/7 
• 2

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides
• Add the 2a and a 
• Distribute 4 to a and -5
• Distribute -4 to a and -5

Solve.

 $6a\ +\ 5a\ =\ -11$  

•  $a\ =\ 0$  

•  $a\ =\ 1$  

•  $a\ =\ -1$  

• None of these

 $-5\left(4x\ -\ 2\right)\ =\ -2\left(3\ +6x\right)$  

•  $x\ =\ 2$  

•  $x\ =\ 8$  

•  $x\ =\ -2$  

•  $x\ =\ -8$  

 $5\left(2x\ +\ 6\right)\ =\ -4\left(-5\ -2x\right)+\ 3x$  

•  $x\ =-20$  

•  $x\ =\ 20$  

•  $x\ =-10$  

•  $x\ =\ 10$
