Multi Step Equations

2x - 3 + 4x = 27

• 12
• 4
• 5
• 15

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

 $24\ =\ 3\left(3x\ -7\right)$ 

•  $x\ =\ -9$  

•  $x\ =\ 5$  

•  $x\ =3$  

•  $x\ =\ 7$  

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

Solve the equation:

3x - 3 = 2x + 9

• x = 12

• no solution

• x = 10

• x = 6
