Equivalent Equations
(+ and -)
Objective: create and identify equivalent equations.
2
Vocabulary
Equivalent: two meanings, numbers, or quantities that are the same.
Examples:
NOTE: look at each side of the equal sign like it's own seperate entity. NOT like a sentence
3
Are the following expressions equivalent?
4 + 2 x 3 - 2 = 44 ÷ 2
?
?
EXAMPLES
2(x + 9) = 24 + 2x - 6
4
Multiple Select
Choose all the equivalent expressions.
12+12−3x=3(x+8)
8−3×3+5=10−12÷2
4x+12=4x+6+6
56÷7=4+3
5
ADDITION PROPERTY OF EQUALITY
Adding the same number to both sides of an equal sign makes an equivalent equation.
8 + 5 = 13
is equivalent to
8 + 5 + 4 = 13 + 4
6
EXAMPLE
If 5 is added to both sides what is the result?
3x - 15 = 32

EXAMPLE
Which equations are equivalent to: 4x - 1 = 6
4x + 6 = 12
4x + 2 = 9
4x - 2 = 7
10
Multiple Select
Which equation(s) are equivalent to 3x - 10 = 6 ?
3x - 6 = 10
3x - 15 = 11
3x = 16
11
EXAMPLE
If 4x - 1 = 6 then 4x + 5 = ?
12

13
SUBTRACTION PROPERTY OF EQUALITY
Subtracting the same number from both sides of an equal sign makes an equivalent equation.
8 + 5 = 13
is equivalent to
8 + 5 - 4 = 13 - 4
14
EXAMPLE
If 6 is subtracted from both sides what is the result?
7x - 22 = 10

EXAMPLE
Which equations are equivalent to: 8x - 3 = 4
8x - 6 = 1
8x - 2 = 3
8x - 4 = 3
18
Multiple Select
Which equation(s) are equivalent to 9x + 7 = -11 ?
9x + 3 = -15
9x + 3 = -7
9x + 11 = -15
19
EXAMPLE
If 3x + 9 = -7 then 3x + 2 = ?
