Answer:
An unknown variable by reversing the process used to form the original equation.
Step-by-step explanation:
The opposite process rule says to solve for - an unknown variable by reversing the process used to form the original equation.
If an equation indicates an operation such as addition, subtraction, multiplication, or division, solve for the unknown variable by using the opposite process.
For example:
Lets say we have to find 
Here 25 is subtracted from both sides of the equation to isolate x.
we get x = 10

Answer: -3 2/3x - 1
Step-by-step explanation:
-2/3x + 5(3/5 - 3/5x) - 12 / 6 * 2
First distribute
-2/3x + 3 - 3x - 12 / 6 * 2
Now divide 12 by 6
-2/3x + 3 - 3x -2 * 2
Now multiply -2 by 2
-2/3x + 3 - 3x - 4
Now subtract 3x from -2/3x
-3 2/3x + 3 - 4
Now subtract 4 from 3
-3 2/3x - 1
Answer:
8
Step-by-step explanation:
Solve for x:
x - 8 = 0
Hint: | Isolate terms with x to the left hand side.
Add 8 to both sides:
x + (8 - 8) = 8
Hint: | Look for the difference of two identical terms.
8 - 8 = 0:
Answer: x = 8
Hello from MrBillDoesMath!
Answer:
Choice D, x-2
Discussion:
Observe the the highest order term in the numerator is x^4 and the highest order term in the denominator is x^3. So the highest order term in their quotient is x^4/x^3 = x. Choice D is the only possible answer as all other choices start with x^2

Answer:
40
Step-by-step explanation:
FAC = FAE + EAD +CAD
We know FAC = 180 and CAD = 50 and EAD = 90
180 = FAE + 90 +50
Combine like terms
180 = FAE + 140
Subtract 140 from each side
180-140 = FAE +140-140
40 = FAE
