What is the solution?
5/100 + y = 70/100
Subtraction Property of Equality.
Subtract 5/100 from both sides
y = 70/100 - 5/100
y = 65/100
What property of equality would you use to find a solution to the equation?
What is the solution?
i + 2 = 11
Subtraction Property of Equality.
Subtract 2 from both sides
i = 11 - 2
i = 9
What property of equality would you use to find a solution to the equation?
What is the solution?
p + 700= 800
Subtraction Property of Equality.
Subtract 700 from both sides
p = 100
What property of equality would you use to find a solution to the equation?
What is the solution?
n - 14= 24
Addition Property of Equality.
Add 14 to both sides
n = 38
What property of equality would you use to find a solution to the equation?
What is the solution?
180 - a = 300
Subtraction Property of Equality.
Subtract 180 from both sides
-a = 120
a is the opposite of -a
So a =-120
What property of equality would you use to find a solution to the equation?
What is the solution?
30 = z + 15
Subtraction Property of Equality.
Subtract 15 from both sides
z = 30-15
z = 15
What property of equality would you use to find a solution to the equation?
What is the solution?
j- 7 = 10
Addition Property of Equality.
Add 7 to both sides
j = 10 + 7
j = 17
What property of equality would you use to find a solution to the equation?
What is the solution?
120 + a = 30
Subtraction Property of Equality.
Subtract 120 from both sides
a = -90
What property of equality would you use to find a solution to the equation?
What is the solution?
6/10 + r = 8/10
Subtraction Property of Equality.
Subtract 6/10 from both sides
r = 2/10
What property of equality would you use to find a solution to the equation?
What is the solution?
7.5-p=2.5
Subtraction Property of Equality.
Subtract 7.5 from both sides
-p = 5
a is the opposite of -a
So p = -5
5
What property of equality would you use to find a solution to the equation?
What is the solution?
1/3 + s = 2/3
Subtraction Property of Equality.
Subtract
1/3
from both sides
s = 2/3 -1/3
s = 1/3
What property of equality would you use to find a solution to the equation?
What is the solution?
g - 11= 23
Addition Property of Equality.
Add 11 to both sides
g = 23+11
g = 34
what is it called when you see one of these 3
exponent
Solve using order of operations
3 + 4 x 10
Multiplication first 4 x 10 = 40
Then add 3
40 + 3 = 43
