You can isolate the variable by subtracting 6 from both sides.
e.g.
x + 6 = 13
- 6 - 6
Now we have x = 7, which not only isolates the variable but solves for x.
If you don't know why we can subtract from both sides, look up the Addition Property of Equality and Subtraction Property of Equality.
You would need 20 cups of whole-wheat flour
Reason is you do 16/4 which equals 4
Given 4 you would do 4*5 which will give you 20!
Let's solve this equation by step by step.
Layout equation.
−10+2x+3(5−x)=2(x−2)
Step 1: Simplify both sides of the equation.
−10+2x+3(5−x)=2(x−2)
−10+2x+(3)(5)+(3)(−x)=(2)(x)+(2)(−2)(Distribute)
−10+2x+15+−3x=2x+−4
(2x+−3x)+(−10+15)=2x−4(Combine Like Terms)
−x+5=2x−4
−x+5=2x−4
Step 2: Subtract 2x from both sides.
−x+5−2x=2x−4−2x
−3x+5=−4
Step 3: Subtract 5 from both sides.
−3x+5−5=−4−5
−3x=−9
Step 4: Divide both sides by -3.
-3x/-3=-9/-3
So the answer is x=3.

Hope this helps!! :))
It took me awhile, but using the Rational Root Theorem and then synthetic division I got the first root. If you don't know the RRT you'll be in heaps of trouble doing this type of problem. I found the first root to be (x+6), then I did it again and got another root of (x+6) and the third one was (x-5). So the roots of this polynomial (and there are 3 because this is a 3rd degree polynomial) are (x+6) with a multiplicity of 2, and (x-5).
