Rules of Integers
positive x positive =
positive
5x + 5x
10x
8 ( 2x + 5)
16x + 40
2 + x = 5
x=3
2x > 8
x > 4
negative/positive=
negative
2x + 3x + 2 + 10
5x + 12
10 ( x + 5)
10x + 50
v - 10 = -9
x=1
x - 10 < 32
x < 42
-10+ 8=
-2
5x -4x + 5
1x + 5
-4 ( 5 - 3x)
-20 + 12x
22=-11k
x=-2
x/-2 > 9
x < -18
-20/-5=
4
-3x - 6x -5 - 8
-9x - 13
-5 ( -x - 20)
5x+100
-2=x/12
x=-24
-6x > -18
x < 3
negative x negative =
positive
-10x + 5x + 6x - 20x + 1 + 10
-19x +11
To distribute means to what?
multiply
-10=x-21
x=11
x/-6 < 5
x > -30
