I am not sure what the question is, but heres my 2 cents.
You know what? Never mind. I don't get the question at all. In order to use substitution, you must totally isolate a variable to 1 side, and only have the variable on 1 side. Then you substitute it. Ex:
2y+4x-5z=45
2z+x-4y=54
Isolate x in the 2nd equation, as it is easier:
x=54-2z+4y
Now, substitute it:
2y+4(54-2z+4y)-5z=45
Got it? I might have done something wrong.

No. The word "order" has various meanings in math, but I don't think this is one of them.

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.

How do you solve system of equations by using the substitution method?
To solve a system of equations using the substitution method, first, solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation to eliminate that variable. This will result in a single equation with one variable, which can be solved for its value. Finally, substitute this value back into the original equation to find the value of the other variable.

Solve this system of equations using the addition method x plus y equals 6?
When talking about a "system of equations", you would normally expect to have two or more equations. It is quite common to have as many equations as you have variables, so in this case you should have two equations.
How do you solve systems of equations by using elimination?

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.?
When using the substitution method to solve a nonlinear system of equations, the first step is to isolate one variable in one of the equations, if possible. This allows you to express that variable in terms of the other variable. You can then substitute this expression into the other equation, transforming the system into a single equation with one variable, which can be solved more easily. Once you find the value of one variable, you can substitute it back to find the other variable.
