Solving Linear Equations

Solve:
3(x - 2) = 18

• 6.7
• 4
• 8
• -4

Solve:
7x + 19 = -2x + 55

• 4
• 14.8
• 8.2
• -4

What is the first step in solving for w in the equation 3w + 5 = 14?

• Add 5 to both sides of the equal sign

• Divide by 3 on both sides of the equal sign

• Subtract 5 from both sides of the equal sign

• Multiply by 3 on both sides of the equal sign

Solve for x:
10 = 3x -12

• 22/3
• 2/3
• 10/9
• 8

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

 $Solve\ for\ y$  

 $3y\ -\ 6\ =\ 30\$  

•  $y\ =\ 8$  

•  $y\ =\ 12$  

•  $y\ =\ 16$  

•  $y\ =\ 4$  

 $21=3+4n+5n$  

• 9

•  $-7$  

• 6

• 2

The objective when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• Combine Like Terms.
