In algebra we consider x,y and z are variables.
x+y
The answer to the equation y x - x a would be x(y-1). When letters are used in a math expression, this is a form of math called Pre-Algebra or Algebra.

Suppose x and y are two POSITIVE numbers so that -x and -y are negative. Then a negative minus a negative = (-x) - (-y) = -x +y If x > y the answer is negative If x = y the answer is zero If x < y the answer is positive

x - -y = x + y.
Suppose x and y are two POSITIVE numbers so that -x and -y are negative. Then a negative minus a negative = (-x) - (-y) = -x +y If x > y the answer is negative If x = y the answer is zero If x < y the answer is positive
It equels 10* * * * *The answer depends on the values of x and y.
It is simply: yx which in algebra means y times x
y=x-2 y=x+4
Given two numbers, x and y their difference is |x - y|. |x - y| = x - y if X ≥ y and |x - y| = y - x if x < y
A negative minus a negative turns the latter into a plus positive,for example -6 minus -3 would be :-6 ++ 3 = -3A minus negative always turns into a plus positive...To get more Specific:Suppose x and y are two POSITIVE numbers so that -x and -y are negative. Then a negative minus a negative = (-x) - (-y) = -x +yIf x > y the answer is negativeIf x = y the answer is zeroIf x < y the answer is positive
Your question is like this:X+Y=15, X-Y=5, (X x Y)-X+Y= ?According to my calculations, X=10 and Y=5, therefore (X x Y)-X+Y= 45.
