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) = 3
3(2x - 9) = 3
6x-27=3
6x=30
x=5
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 + x + 2 = -30
3x + 4 + x + 2 = -30
4x+6=-30
4x=-36
x=-9
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) = 2
2 +9(x-1) = 2
2+9x-9=2
9x-7=2
9x=9
x=1
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 = 31
2(x + 3) + 1 = 31
2x+6+1=31
2x+7=31
2x=24
x=12
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. Get variables and constants opposite sides (addition and subtraction)
3. Isolate your variable (multiplication and division)
h/-3 + 6 = -4
h/-3+6=-4
h/-3=-10
h = 30
3(5x - 2) + 9x - 4
24x - 10
2x - 1 +2(x - 1) = - 7
2x - 1 +2(x - 1) = - 7
2x-1+2x-2=-7
4x-3=-7
4x=-4
x=-1
