What is the first step to solve this equation?
x - 5 = 7 - 2x

• Add 7 to both sides of the equation

• Add 2x to both sides of the equation

• Subtract 2x from both sides of the equation

• Subtract 5 from both sides of the equation

Name the first property you will use to solve this equation:
3(x – 7) = 42

• Multiplication Property of Equality
• Commutative property
• Associative Property
• Distributive Property

If 17x = 68, then x = 4.

• Addition Property of Equality

• Subtractions Property of Equality

• Multiplication Property of Equality

• Division Property of Equality

Solve for x:
2(3x + 4) + 2 = 4 + 3x

• 2
• -2/3
• 10
• -2

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

• 1
• 2
• 3
• 4

Solve for x.

 $-\frac{5}{4}\ =\ -\frac{7}{2}x\ +\ \frac{1}{2}$  

•  $x\ =\ -\frac{3}{14}$  

•  $x\ =\frac{1}{2}$  

•  $x\ =-\frac{14}{7}$  

•  $x\ =\frac{3}{14}$  

 $Solve\ for\ n.\ \ \ \ \ \ \ \ \ \frac{5}{3}\ =\ -\frac{1}{2}n\ +\ 1$  

•  $\frac{3}{4}$  

•  $-1\ \frac{1}{3}$  

•  $-4$  

•  $-15$
