Translate this word problem as a system of equations and then solve using substitution?
A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
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 ordered pair for 3x 5y equals 21 and -9x 4y equals -6?
To find the ordered pair for the equations (3x + 5y = 21) and (-9x + 4y = -6), we can solve this system of equations. By using substitution or elimination methods, we find that (x = 3) and (y = 2). Thus, the ordered pair is ((3, 2)).
What methods can be used to solve a system of equations?
The answer depends on the nature of the equations. For a system of linear equations, the [generalised] inverse matrix is probably simplest. For a mix of linear and non-linear equations the options include substitution, graphic methods, iteration and numerical approximations. The latter includes trail and improvement. Then there are multi-dimensional versions of "steepest descent".

What are the advantages and disadvantages of solving a system of equations by substitution?
The substitution method for solving a system of equations is advantageous because it can be straightforward, especially when one equation is easily solvable for one variable, allowing for direct substitution. It can also provide clear insights into the relationships between variables. However, its disadvantages include the potential for increased complexity when dealing with more variables or complicated equations, and it may be less efficient than other methods, like elimination, for larger systems. Additionally, if the equations are not easily manipulated, it can lead to errors in calculation.
What is the first step in solving the following system of equations by substitution?
The first step is to show the equations which have not been shown.
When using the substitution method to solve a nonlinear system of equations you should first see if you can one variable in one of the equations in the system?
isolate

What is the solution to system of equations in which the two lines given have different slopes?
When two lines in a system of equations have different slopes, they intersect at exactly one point. This means the system has a unique solution, which corresponds to the coordinates of the intersection point of the two lines. You can find this point by solving the equations simultaneously using methods such as substitution or elimination.
What are the methods to solve a system of equations?
There are several methods to solve a system of equations, including the substitution method, where one equation is solved for one variable and substituted into the other; the elimination method, which involves adding or subtracting equations to eliminate a variable; and graphical methods, where the equations are represented as lines on a graph and the intersection point(s) represent the solution. Additionally, matrix methods, such as using the inverse of a matrix or row reduction (Gaussian elimination), can also be employed for larger systems. Each method has its advantages depending on the specific system being solved.
How do you solve 2x plus 2y equals 4 and 4x plus y equals 1?
2x + 2y = 44x + y = 1There are many methods you can use to solve this system of equations (graphing, elimination, substitution, matrices)...but no matter what method you use, you should get x = -1/3 and y = 7/3.
