Answer:
2x– 3y = –18
3x + y = -5
Converting the equation in slope-intercept form
2x-3y= -18
-3y= -2x-18
-3y= -(2x+18)
3y=2x+18
y=(2x+18)/3
And for equation 2
y= -5-3x
For plotting the graph, the online graphing calculator desmos.com can be used.
The points can be calculated by putting negative and positive values of x in both equations.
The graph is attached as a picture.
As we can see from the graph that two lines intersect at (-3,4) so it is the solution of the given system of linear equations.
Answer:
[tex](-3,4)[/tex],
Step-by-step explanation:
The given system of equations is
[tex]\left \{ {{2x-3y=-18} \atop {3x+y=-5}} \right.[/tex]
To solve this system, we could multiply the second equation by 3, and solve for x:
[tex]\left \{ {{2x-3y=-18} \atop {9x+3y=-15}} \right.\\11x=-33\\x=\frac{-33}{11}=-3[/tex]
Now, we replace this value in a equation to find y-value:
[tex]3x + y = -5\\3(-3)+y=-5\\-9+y=-5\\y=-5+9\\y=4[/tex]
Therefore, the solution for the system is [tex](-3,4)[/tex], you can observe this in the graph attached.
