Solving Equation Test next week

Addition Equation - add the opposite to both sides
EX: 2 + m = -3
+ -2 = +-2
m = -5

Subtraction Equations - Turn into an addition equations and add the opposite to both sides.

w - 2 = 5
w + -2 = 5
+ 2 = +2
w = 7

Multiplication and Division Equation- do the opposite operation to both sides.

Ex:
5w = 15
5w = 15
-- = --
5 = 5
w = 3


EX:
y = -25
--
5
5*y = -25 *5
--
5
y = -125
