Multi-Step Equations HW

Solve the equation:

8v - 4(v + 8) = 8

• 2

• 10

• 4

• -4

Solve the equations:

3x + 2(4x - 4) = 3

• 4

• 3

• 2

• 1

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

• 1
• 2
• 3
• 4

5(x - 3) + 2x = 27

• 3
• 42/15
• 30/7
• 6

-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

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

•  $x\ =\ 2$  

•  $x\ =\ 8$  

•  $x\ =\ -2$  

•  $x\ =\ -8$  

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

•  $x\ =-20$  

•  $x\ =\ 20$  

•  $x\ =-10$  

•  $x\ =\ 10$
