What operation would you use to solve this equation, x + 7 = 13
Subtraction
What operation would you use to solve this equation, x - 7 = 13
What is addition?
x+7=19
x = 12
x − 5 = 11
x = 16
This Math process makes you UNDO or find the opposite of an operation.
INVERSE OPERATION
a + 14 = 18
a= 4
x - 13 = 5
x=18
y+15=32
y = 17
m - 18 = 15
m = 33
What the the vocabulary of this meaning?
A math sentence with an equal sign.
Equation
m + 19 = 34
m= 15
m - 39 = 19
m=58
a + 6 = 18
a = 12
45 = h - 37
h = 82
A letter that stands for a number.
Variable
t + 24 = 68
t=44
p - 76 = 29
p=105
n+20=45
n = 25
27 = w - 8
w = 35
The number that makes the equation true
Solution
p + 48 = -87
p=-135
t - 87 = -68
t = 19
e + 9 = -14
e = -23
w = -2
