End the Inequality!
How do you read this inequality symbol:
<
less than
-7m = 63
-7m = 63
m=-9
6m – 5m + 1
m+1
3(2x - 9) = 3x
3(2x - 9) = 3x
6x-27=3x
-27=-3x
-9=x
Graph the solution set to
x > 4
See teacher drawing
___ ___ have the same variable or exponent. We combine these together
like terms
n/7 = -8
n= -56
-6(4x - 5)
-24x + 30
3x + 4 = -30(x+2)
3x + 4 = -30(x+2)
3x+4 = -30x-60
33x=-64
x=-64/33
Solve the inequality.
2x> -6
x > -3
_________ are positive and negative whole numbers. Like -1, 0, 9, -4...
integers
-2k-4=8
-2k-4=8
-2k=12
k=-6
9 -3d(6 + 9)
9 - 45d
or
-45d + 9
2 +9(x-1) < 2x+1
2 +9(x-1) < 2x+1
2+9x-9<2x+1
9x-7<2x+1
7x-7<1
7x<8
x<8/7
Solve the inequality.
3x-3 <= 12
Express your answer correctly in words
x is less than or equal to 5.
The first step to follow when solving multi-step equations
Simplifying is the first step to follow when solving multi-step equations
2x + 6 = 6
2x=0
x=0
4(5f + 3) + 11
20f + 23
-2(x + 3) + 1 >= 3(x+1)
-2(x + 3) + 1 >=3(x+1)
-2x-6+1>=3x+3
-2x+7>=3x+3
-5x+7>=3
-5x>=-4
x<=4/5
How many solutions do inequalities have?
infinite
The three steps to solving multi-equations are 1. ___ 2. ___ 3.____
The three steps to solving multi-equations are
1. Simplify (with distributive property and combining like terms)
2.Add and subtract to get variables and constants opposite sides
3. Multiply or divide to isolate your variable
h/-3 + 6 = -4
h/-3+6=-4
h/-3=-10
h = 30
3(5x - 2) + 9x - 4
24x - 10
2x - 2 =2(x - 1)
2x - 2 =2(x - 1)
2x-2=2x-2
