Intro to second semester

Page 1

equations and solutions

~ solutions: a value for a variable that makes an equation true

~solving and equation = the process of finding the solution. We want the variable by itself.

~Inverse operations to "undo"

Page 2

additon property

~if you add the same number to each side it's still equal.

Page 3

subtraction property

~f you subtract the same number from each side of the problem the sides remain equal

~ subtract from both sides when adding

Page 4

writing equations

~variables are used to represent unknown

Page 5

reciprocial

~same thing just flipped/flopped

Page 6

division property of equality

~ when you divide each side of an equation by the same number

~nonzero the sides that remain equal

~you can divide by nonzero just not zero

Page 7

Multipliacation property of equality

when you multiply each side of an equation by the same nonzero number, the two sides remain equivalent
