How to isolate x:

we have this equation:

3x + (3 x(times) 3) = 9

Step 1:
Remember BEDMAS
Brackets
Exponents
Division
Multiplication
Addition
Subtraction

In this equation, we want to find the value of x, to find the value, we will isolate it.

Step 2:
Remember Bedmas
brackets comes first in this equation
3 x 3 = 9
Now we have:
3x - 9 = 9

Step 3:
Let's turn things around
Let's put x on the other side
When we reverse the numbers, we do the same with the operations
3x = 9-9
3x = 0

Step 4:
Continue turn things around
x = 0

Step 5:
Now, confirm the equation given that x = 3
3 x 0 + (3 x 3) = 9
3 x 0 + 9 = 9
0 + 9 = 9
9 = 9
Now we know that x = 0!
