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
When solving a system of equations by substitution what is meant by a useless result 12 equals 12?
In the context of solving a system of equations by substitution, a "useless result" like 12 equals 12 indicates that the two equations are actually dependent, meaning they represent the same line or have infinitely many solutions. Instead of finding a unique solution, you end up with a tautology that confirms the equations are equivalent. This suggests that any solution that satisfies one equation will also satisfy the other, leading to an infinite set of solutions rather than a single point of intersection.

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
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
What does X and Y equal in the equations 2X equals 3Y and 4X-3Y equals 12?
y = 4, x = 6

What prefix equals 1 trillion in the metric system?
If you mean the American trillion - a 1, followed by 12 zeroes - the prefix is tera.
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
Solve these equations 4x equals -12?
