What should I deal with first?
I’ve got the plus or minus thirst
We see 8 which equals 2 times X minus 4
Use the inverse
Add a 4 to every side
And Watch them cancel on the right
Hey add this 4, 8 don’t be shy
Chorus:
What you do to one side
You gotta do to the other
If you’re subtracting something here
Then you subtract the same number
To isolate the variable
Behind the equal sign, sign, sign
Just do the two-step, ya’ll
To solve this equation
Undoing what’s been done
By using inverse operations
Just isolate the variable
And tell us what you find, find find
Behind the equal sign
In step two we multiply or divide
And operate the inverse, fine
Now 12 which equals 2 times X
Divide the 2 on every side
Creates a fraction on the left
And it cancels on the right
Now take the 12 over the 2
And simplify
You’ll wanna check your answer
By substituting the value of X
Back into the original e-equation
The two expressions should be equal now…
