Distributive Property
What does this turn into?
2(x-13)
2x-26
What does this turn into?
2x+6+4x
4x+6
What should you do FIRST in this situation?
2(3x+6)=4(x+12)
Use the distributive property to get rid of the parenthesis
What does this turn into?
3(3x-2) = 4(5x+2)
9x-6 = 20x+8
What does this turn into?
3x-5+21=4x+3+5x
3x+16=9x+3
What should you do SECOND in this situation?
2(3x+6)=4(x+12)
Move the variables to the left by subtracting 4x on both sides
Solve for X
4(x-2)=x+10
X=6
Solve for X
6x-30+2=4+2x
X=8
What should you do THIRD in this situation?
2(3x+6)=4(x+12)
Move the constants to the right by subtracting 12 from both sides
Solve for X
8(12-x)=3(k+21)
X=22
Solve for X
-7x-3x+2=-8x-8
X=5
What should you do last in this situation?
2(3x+6)=4(x+12)
Divide both sides of the equation by 2 to get x=18
Solve for X
2/3(x-6)=5x-43
Solve for X
-10+x+4-5=7x-5
X=-1
What do I do FIRST?
.02x+.3=4x+6
