What does the answer 12 equals 12 in a system of equations mean?

It probably means that one of the equations is a linear combination of the others/ To that extent, the system of equations is over-specified.

What is the solution of this system 3x plus 4y equals 5 x-4y equals 7?
Add the two equations and get 4x = 12 so x = 3 and y = -1
What is 12 n in a d?
It equals number in a a dozen. source:see how well you can do on a equations test
Is the system of equations 3x-6y equals 12 and 2x-4y equals 3 dependent consistent inconsistent or independent?
The system is inconsistent because there is no solution, i.e., no ordered pair, that satisfies both equations. You can see that this will be the case by seeing that their graphs have the same slope (2) but different y-intercepts (2 and 3/4 respectively). So the lines are parallel and will not intersect.

What is the common point of these equations 2x plus 3y equals 12 and x - 3y equals -3?
(3, 2) because x = 3 and y = 2
Solve the system of equations 3x plus 4y equals 12 2x plus 4y equals 8?
x = 4 and y = 0

Use the substitution method to solve the system of equations x plus 2y equals 12 and y equals x plus 3?
x+2(x+3) = 12 x+2x+6 = 12 x+2x = 12-6 3x = 6 x = 2 and y = 5
How are math expressions and math equations different?
Math equations have an equals sign such as: 7+5=12 or 9x6=47+7 Math expressions do not have a equals sign such as: 43-27 or 8x40
What does X and Y equal in the equations 2X equals 3Y and 4X-3Y equals 12?
y = 4, x = 6

What is an equation that equals 12?
No equation equals 12, but there are an infinite number of equations for which 12 is a solution. Here are a few: x + 1 = 13 2x - 6 = 18 x2 = 144 x = log(1,000,000,000,000)
What is the answer to 3.25p-14 equals 12?
Equations do not have "answers", a myth which is reinforced by the way algebra tends to be taught in schools. You can, however, solve equations for different things, particularly variables. If by the "answer", you mean the value of p, then we can solve it like this: 3.25p - 14 = 12 3.25p = 26 p = 26/3.25 p = 8

What is equation of 3x plus 2y equals 8 and 5x plus 2y equals 12?
Both of them are equations!The solution is (x, y) = (2, 1).
