Rules
What is the first step in solving multi step equations?
Distribution
2(x + 3) = 22
x = 8
| x + 5 | = 9
x = 4 , x = -14
2x > 10
x > 5
Graph x > 2
See board
How many solutions will you have when solving an absolute value equations?
2
2x + 3x - 4 = 1
x = 1
| x - 6 | = 10
x= 16 , or x = -4
2x + 3 < 19
x < 8
Solve:
2x - 3 = 3x - 12
x = 9
What should I do to make sure my solutions are correct?
Check my work by substituting the values back into the original question.
5 (x + 6) = -9x + 2
x = -2
3 | x - 4 | = 21
x = 11, or x = -3
-4x > 16
x < -4
| w - 1 | = 4
w = -3 or w = 5
When the "alligator" eats the number, which way should you shade?
To the left. (Less than)
8(1 + 5x) + 5 = 13 + 5x
x = 0
6 | x - 3 | = 42
x = 10 or x = -4
2(4x - 5) > 7x + 1
x > 11
Solve:
3x > 7x - 4
x < 1
When solving an inequality, when should you flip your sign?
When dividing or multiplying by a negative.
2(3x - 4) + 8 = 6
x = 1
4 | x + 2 | + 3 = 7
x=-1 or x=-3
-3x + 4 < 2x +19
x > -3
|100| = x
x = 100
