Ax + by = ay + bx
ax - ay + by - bx = 0
a(x - y) + b(x - y) = 0
(a + b)(x - y) = 0

Great !
When I saw this question, I was about to say "No it doesn't. Not unless A=B."
But "Blackfireweb" developed a much more in-depth analysis. Unfortunately, there was a
small error in his algebra, in the third line, where he collects like terms from the second line.
Repeating Blackfireweb's work:
Ax + By = Ay + Bx
A(x - y) + B(y - x) = 0
A(x - y) - B(x - y) = 0
(A - B) (x - y) = 0
-- The equation can only be true for all (x, y) if ( A = B ).
-- Otherwise, it's only true at a point where ( x = y ).
What this really means is: Whatever numbers you pick for 'A' and 'B', if you write an equation
such as appears in the question and then massage it a bit, you always find that you have
the equation ( Y = X ), and you realize that we have all been making something complicated
out of something simple.
Notice that the "question" doesn't even ask any question. It just makes a statement.
To which we reply: "OK. That's the equation ( Y = X ). So what ?"

Ax plus b equals bx plus c then x equals?
Ax + B = Bx + C Ax - Bx = (C - B) x (A - B) = (C - B) x = (C - B) / (A - B)
AX plus BY equals AY plus BX what is the general equation?
Assuming the question is about chemical reactions (rather than mathematics where it is placed), it is a double displacement.
What is Ax plus bx plus c?
Ax + Bx + C is called an algebraic expression.
Factorize x2 plus bx plus ax plus ab?
x2+bx+ax+ab = x2+ax+bx+ab = x(x+a)+b(x+a) = (x+a)(x+b)
Ax plus bx plus c equals 0?
x = -c/(a+b), provided a+b is not 0
Ax plus b equals bx plus c then x equals?
Ax + B = Bx + C Ax - Bx = (C - B) x (A - B) = (C - B) x = (C - B) / (A - B)
AX plus BY equals AY plus BX what is the general equation?
Assuming the question is about chemical reactions (rather than mathematics where it is placed), it is a double displacement.
Solve for x and y. ax plus by equals a-b bx-ay equals a plus b plus b?
Your two equations are: AX + BY = A - B BX - AY = A + B + B Because you have four variables (A, B, X, Y), you cannot solve for numerical values for X and Y. There are a total of four answers to this question, solving each equation for X and Y independently. First equation: X = (A - B - BY)/A Y= (A - B - AX)/B Second equation: X = (A +2B +AY)/B Y = (BX - A - 2B)/A
What type of reaction has the general form AX plus BY -- AY plus BX?
A double replacement reaction.
What type of reaction is represented by the general form AX plus BY BX plus AY?
Double Replacement
What is Ax plus bx plus c?
Ax + Bx + C is called an algebraic expression.
Factorize x2 plus bx plus ax plus ab?
x2+bx+ax+ab = x2+ax+bx+ab = x(x+a)+b(x+a) = (x+a)(x+b)
Ax plus bx plus c equals 0?
x = -c/(a+b), provided a+b is not 0
How do you factor ax ay-bx-by?
(a - b)(x + y)
What is 3x squared plus 6x-3 equals 8 in the form of Ax squared plus Bx plus C equals 0?
It is: 3x2+6x-11 = 0
What is the factor of 3a plus ax plus 3b plus bx?
3a+ax+3b+bx = 3(a+b)+(a+b)x = (a+b)(3+x)
What will be the X in terms of a and b if Cos aX equals 1 plus bX and a and b are constants?
a = 0, b = 0.
