Test Ch7

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

7 + ^a⁄₃ = 5

• a= -2
• a= -6
• a= 3
• a= 15

Solve the equation for x:
2x + 3x + 4 = 44

• x = 8
• x = 9
• x = 10
• x = 11

3(3x - 6) = 18

• x = 4
• x = -4
• x=8
• x= -12

-11 + 3(b + 5) = 7

• b = 1
• b= -1
• b = 3
• b = -3

Solve for x.
4(2x+8)-3x = 47

• 13
• 2
• 3
• 7.8

Solve.

 $6a\ +\ 5a\ =\ -11$  

•  $a\ =\ 0$  

•  $a\ =\ 1$  

•  $a\ =\ -1$  

• None of these

 $4x\ +\ 6\ +\ 3\ =\ 17$  

•  $x\ =\ 6.5$  

•  $x\ =\ -6.5$  

•  $x\ =\ -2$  

•  $x\ =2$  

 $24\ =\ 3\left(3x\ -7\right)$ 

•  $x\ =\ -9$  

•  $x\ =\ 5$  

•  $x\ =3$  

•  $x\ =\ 7$
