M3-1.1 Equations with Variables on Both Sides

/ / #

Examples: Notes:

EQ: How can you solve equations when there are variables on both sides of the equation?

Addition Property of Equality• If a = b, • then a + c = b + c

Subtraction Property of Equality• If a = b, • then a - c = b - c

Multplication Property of Equality• If a = b, • then ac = bc

Division Property of Equality• If a = b and c ≠ 0• then

a = 3 & b = 3c = 2

3 + 2 = 3 + 2

a = 3 & b = 3c = 2

3 - 2 = 3 - 2

a = 3 & b = 3c = 2

3(2) = 3(2)

a = 3 & b = 3 c = 2

Inverse Operation: Operations that UNDO each other.• Addition & Subtraction• Multiplication & Division

Additive Identity Property of 0• add a number to zero, the result, or sum, is

that original number

MIPOO = Multiplicative Identity Property of One:• multiply a number by 1, the result, or

product, is that original number.
