100
Which one is the variable? (hint - it will be a letter in the equation) x + 6 = 10
(? + 6 = 10 like in elementary school)
x is the variable.
It is the unknown.
100
Which one is the coefficient 4x?
4 is the coefficient. It is the number part that is in front of the variable x
200
Which one is the Constant?
x+6=10
6 is the Constant
The Constant is the fixed number being added, subtracted, multiplied or divided.
200
What is the simplified form of an equation?
a) 4x+2y-2x
b) 2x+ 2y
Reminder to pay attention to the - signs in front of the numbers. The - sign goes with the number it is in front of.
The simplified form of the equation is when all the terms are combined.
b) 2x +b 2y
300
In this equation what is the operator?
x + 6 = 10
+ is the operator
The operator is the math operation being performed.
so if it was x - 6 = 10 , operator is -
The operator can be add/subtract/multiplication/division
400
What is the inverse operation mean?
and..
What is the inverse/opposite of +, - , *, /
It means to do the opposite of what is happening to the variable
The inverse/opposite of operations is the following:
The opposite of + addition is -
The opposite of - subtraction is +
The opposite of multiplication 4x7 is division
The opposite of division 6/2 is multiplication
500
Whatever you do to one side of the equation you have to do to the ________ side of the euqation
other side of the equation (the other side of the equal sign.
5 + x = 13
-5 -5
x = 8
600
The goal is to isolate the variable. Get it on one side of the equation by itself.
x = 6
x=6
