3x + -1 = -5x + 4
Move the variables (which are like terms) to one side. Add 5x to both sides. 8x + -1 = 4
100
3x + 2(5x - 7)
13x - 14
100
-3 - 4x = 21 - 8x
x = 6
100
16 − 2x = −8 + 4(x − 3)
x = 6
100
The vocabulary word that means a letter that represents a number.
What is a variable?
200
3x + 5x + 2 = 6x - 1
Add 3x + 5x and to equal 8x.
8x + 2 = 6x - 1
200
-5 + 5(x + 4)
5x +15
200
2x + 12x - 8 = 11x + 1
x = 3
200
−6(3 − 6x) = −18 + 4x
x = 0
200

What is inverse?
300
11x +7 = -70
Isolate the variable by moving the constants to the same side. 11x = -77
300
2x - (9x - 4)
-7x + 4
300
-9x + 8 = 48 + x
X = -4

5 − (8x + 5) = −4(1 + 3x)
x = -1
300
A vocabulary word that means that a number has a fixed value.
What is a constant?

3(x - 1) = 4x
Use the distributive property: 3x - 3 = 4x
400
11 - (3x - 6) + 2(4x +5) - x
4x + 27
400
-6x + 14x - 280 = -9x - 127
x = 9
400
3(x − 6) = −5x − (7 + 3x)
x = 1
