How to solve a Linear Equation

7(2x-1)-5x = x+25 1. Utilize the distributive
    property to dispose of the
    parentheses
14x-7-5x = x+25
 2. Next combine your terms that
    are the same
9x-7=x+25
 -x   -x
 3. Then you must get all of the x's
    to one side.
8x-7=25
 4. Finally you must divide the
    number in front of the x's to
    get your final answer

 
 
 

Solve   A=(b1+b2)h        for b
2


 
2A=(b1+b2)h
1. First multiply both sides by 2
2A=b1+b2
  h		 2. Next you must divide each side
    by h
2A=b2=b1
 h		 3. Finally subtract b2 from each
    side of the equation

 

How to Find the Equation for a Line
Given Slope and a point

Slope = 3 through (2,9)
 1. This is your problem
y-9=3(x-2)
 2. Plug in your slope and point
y-9=3x-6
 3. Use the distributive property to
    get rid of the parenthesis.
y=3x+3
 4. Add nine to both sides.
    This is your final answer.
