Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.
y = 2x + 5 x = 1
(2,3)
If it has infinite number of solutions that means that any ordered pair put into the system will make it true. I believe the relationship of the graphs question your asking is that tooth equations will probably be the same line
The first step is to show the equations which have not been shown.
Simultaneous equations can be solved using the elimination method.

There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.
If you mean: y = 6x-4 and y = 7x-7 then by substitution x = 3 and y = 14

Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).
True. To solve a three variable system of equations you can use a combination of the elimination and substitution methods.
To solve a system of two equations, you can use one of three methods: substitution, elimination, or graphing. In the substitution method, you solve one equation for one variable and substitute that expression into the other equation. In the elimination method, you manipulate the equations to eliminate one variable by adding or subtracting them. Graphing involves plotting both equations on a graph and identifying their point of intersection, which represents the solution.
Yes, a system of linear equations can be solved by substitution. This method involves solving one of the equations for one variable and then substituting that expression into the other equation. This process reduces the system to a single equation with one variable, which can then be solved. Once the value of one variable is found, it can be substituted back to find the other variable.
The first step is to show the equations which have not been shown.
Plug your ordered pair into both of your equations to see if you get they work.
