Activity 2 Quiz Review

What is the first step to solve this equation:

- 3x -11 = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

Solve for x:

7(2x - 4) = 42

• x = 5

• x = 8

• x = 2

• x = 9

Solve for x:

2x - 3 + 4x = 27

• x = 12

• x = 4

• x = 5

• x = 15

What is the first step in solving the following equation?
5t + 19t = 12

• Combine Like Terms
• subtract 19 from both sides
• add 19 to both sides
• divide by 19 on both sides

What is the first step to solve this equation?
3n - 4 = -2 + 2n 

• Add 2n to both sides of the equation

• Add 3n to both sides of the equation

• Subtract 2n from both sides of the equation

• Subtract 4 from both sides of the equation

What is the first step to solve this equation?
3x + 6 = 10 + 3x + 4x 

• Add 4x to both sides of the equation

• Combine like terms 3x and 4x on the same side of the equation

• Add 3x and 6 to get 9x

• Add 6 and 10 to get 16

Solve for b

y = mx + b

• b = y - mx

• b = mx - y

• b = y + mx

• b = ymx

Solve for x

y = mx + b

• $x=\frac{yb}{m}$

• $x=ybm$

• $x=\frac{y+b}{m}$

• $x=\frac{y-b}{m}$

 $p\ =\ 2l\ +\ 2w$  
solve for w

•  $w=\frac{p}{2l}-2$  

•  $w=\frac{p-2l}{2}$  

•  $w=\frac{p+2l}{2}$  

•  $w=2p-l$  

Which property is shown below?
__________________________
