someone mind explaining on how to do these type of problems please

Question

song_of_the_sole · Answer

it says i have to graph and solve the system
3=4y+x
4y=x+3

mathstudent55 · Answer

A system of equations is a set of two or more that may have a solution that satisfies all the equations.
Your system has two equations.
You are looking for an ordered pair that is a solution of both equations.
One method of finding the solution is to graph the system of equations.
Then, if the lines intersect, that is the solution.

Do you know how to graph a linear equation?

song_of_the_sole · Answer

so how would i graph it?

mathstudent55 · Answer

There are several methods. Her is one of them.
You need to graph each equation by itself.

how do i do this?

song_of_the_sole · Answer

so i have to simplify the equation?

mathstudent55 · Answer

Both of your equations are linear equations. That means that their graphs are straight lines. If you find two points for each equation, then you can graph since two points are enough to graph a line.

song_of_the_sole · Answer

how do i graph it then when the equation looks like 
3=4y+x
4y=x+3

mathstudent55 · Answer

Start with the first equation.

$3=4y+x$

You need to find two points that satisfy this equation.
Let's use the x- and y-intercepts.

In the equation above, let x = 0.
Then solve it for y.
Can you do that?
