Your answers are x = 2 & y = 1
Original Equations
x - 2y = 0
3x + 2y = 8
Solve for a variable (x)
x = 2y
Substitute x with its equation
3*(2y) + 2y = 8
6y + 2y = 8
8y = 8
y = 1
Solve for second variable
x = 2*(1)
x = 2
Check your answer
(2) - 2*(1) = 0
3*(2) + 2*(1) = 8

To solve a three variable system of equations you can use a combination of the elimination and substitution methods?
True. To solve a three variable system of equations you can use a combination of the elimination and substitution methods.
Can substitution in math be used to find the exact solution of a system of equations?
yes
Which is most likely the first step in solving a system of nonlinear equations by substitution APEX?
Isolating a variable in one of the equations.
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.
To solve a three variable system of equations you can use a combination of the elimination and substitution methods?
True. To solve a three variable system of equations you can use a combination of the elimination and substitution methods.
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".
Use the substitution method to solve the system of equations Choose the correct ordered pair 2x plus 3y equals 13 x equals 2?
(2,3)
Use the substitution method to solve the system of equations Enter your answer as an ordered pair?
Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.y = 2x + 5 x = 1
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 first step in solving the following system of equations by substitution?
The first step is to show the equations which have not been shown.
What are two symbolic techniques used to solve a system of linear equations in two variables?
I have never seen the term 'symbolic' used in this way. There are 4 methods used to solve a system of linear equations in two variables. Graphing, Substitution, Elimination, and Cramer's Rule.
What is a solution to the following system of equations using substitution -5x plus y equals -5?
-10
Can substitution in math be used to find the exact solution of a system of equations?
yes
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.
Compare the graphical and analytical methods of finding the resultant of two or more vectors?
Graphical methods involve examining charts, pictures, and graphs to determine the answer to a problem. This would be used when finding the solution to a system of equations and graphing all the equations to find points at which they coincide. Analytical methods involve calculating answers without the use of charts or graphs. If one were to solve a system of equations by substitution, this would be an example of an analytically produced solution
Which is most likely the first step in solving a system of nonlinear equations by substitution APEX?
Isolating a variable in one of the equations.
