Finish this sentence: Whatever operation you apply to one side of the equation, you must .....
... apply the same operation to the other side
200
3n = 27
n = 9
200
n/3 - 4 = 6
n = 30
200

The product of 2 and y is 10

2y = 10

200
We always start our box-chart diagram with this
What is the variable
200
When solving 2(n + 5) = 20 algebraically... What is the first step?
We must expand
300
k/5 = 8
k = 40
300
0.2k + 6 = 9
k = 15

The quotient of fifty and five more than a number is ten.

50 / n + 5 = 10

300
In order to solve the equation, we need to _________ the variable
What is to isolate the variable
300

Solve the following expression if x = 22

                  3x - x = ??

44

400
2x = 36.8
x = 18.4
400
c/0.8 + 2 = 17.75
c = 12.6
400

When x is doubled and then 6 is added, the result is 44

2x + 6 = 44

400
We use ________ operations to solve equations
What are inverse operations
