2x + 4 = 8
x = 2
8x + 5 = 6x + 1
x= -2
8x + 12 + 2x
10x + 12
3(2x + 4)
6x + 12
The "Letter" in a math problem is also called what?
Variable
-5x - 4 = 21
x = -5
10x + 18 = 8x + 4
x= -7
2 - 3x + 6 - 2x
-5x + 8
6(-8 - 5v)
-30v - 48
When using distributive property, are you supposed to add, subtract, multiply, or divide?
Multiply
6 = a/4 + 2
x=16
8x - 7 = 8x - 7
I.M.S
3x2 + 5x +1 + x
3x2 + 6x + 1
2x(2x + 7)
4x2 + 14x
Terms that have the same variable, raised to the same power are referred to as what?
Like Terms
-2x -10x + 12 = 18
x = -1/2
15x + 6 = 15x - 2
No Solution
5 + x - 2x2 - 3 - 4x2
-6x2 + x + 2
10(2 - x) + 12x = 44
x = 12
What is our main goal when solving a one, two, or multi step equation? (How do you know when you're done?)
Get the variable by itself
A repair bill for your car is $553.the parts cost $265. The labor costs $48 per hour. write and solve the equation.
x = 6
1/2(6h - 4) = -5h + 1
h = 3/8
10 - 8x - 6x2 + 3x + 3x2 -2 + 4
-3x2 -5x + 12
2(4z-1) = 3(z +2)
z=8/5 or 1 3/5 or 1.6
What's it called when we add, subtract, multiply, or divide on both sides of the equation?
Balancing our Equation
