Question

|| HELP PLEASE!!!||
What is the solution to the system of equations?
5x - 3y = -9,
2x - 5y = 4

Answer 1

\(\large\color{slate}{ \left[\begin{matrix}~5~ & ~-3~ & |&~-9 \\ ~2~ & ~-5~ & |&~4 \end{matrix}\right] }\)

don't know why matrix appears to be good to me, but I would consider that option.

Answer 2

i got y = -2, x= -3 but idk if it's right.

Answer 3

5x - 3y = -9 --->(2)
2x - 5y = 4 --->(-5)
-----------------
10x - 6y = -18 (result of multiplying by 2)
-10x + 25y = -20 (result of multiplying by -5)
-----------------add
19y = -38
y = -2

5x - 3y = -9
5x - 3(-2) = -9
5x + 6 = -9
5x = -9 - 6
5x = -15
x = -3

check..
2x - 5y = 4
2(-3) - 5(-2) = 4
-6 + 10 = 4
4 = 4 (correct)

so x = -3 and y = -2

Answer 4

you got what I got :)

Answer 5

you can always check your answer by subbing it back into either equation to see of they come out equal...if they do, then it is correct

Answer 6

Thank you so much! @texaschic101 & @SolomonZelman

Answer 7

sure thing :) I didn't really do anything...just checked your work and found it to be correct...you did the work

Answer 8

Do you think you could help me with another question? I'm not sure how to do it at all and I just need to be walked through it. Please? @texaschic101

Answer 9

whats the problem ?

Answer 10

:\\

Answer 11

inconsistent means there is no solution...it means that the lines are parallel...they have the same slopes but different y intercepts.
In y = mx + b form, the slope is in the m position and the y intercept is in the b position.

This one is confusing me a little bit...you might want to ask Solomon
