Problem Set PA-1

Solve for n
7 + n =  11

• n= 2
• n=4
• n= 18

Solve for x
5 + 5 + x = 13

• x= 3
• x = 2
• x= 23

To balance an equation, 

• both sides must equal 10
• the right side must be greater
• both sides must be equal

Solve for n:

n + 12 = 20

• n = 8

• n = 32

• n=

Solve for x:

20 - x = 13

• x= 8

• x = 33

• x= 7

Solve for n:

n= 4+ 12

• n = 15

• n = 16

• n = 26

Solve for k:

k + 6 = 9 + 5

• k = 14

• k = 8

• k = 15

Solve for x:

 $7x+8+9x-5$  

•  $16x+3$  

•  $19x+3$  

•  $18x-7$  

•  $9x-7$  

 $Solve\ for\ k:\ \ \ \ \ \ \ \ \ \ 3\left(k-6\right)=30$  

•  $k\ =\ 30$  

•  $k\ =\ 16$  

•  $k\ =\ 18$  

•  $k\ =-1$  

What is the solution of the equation:
 2x + 9 = 6x – 7

• x = 2
• x = 3
• x = 4
• x = 5
