Question

2x - y - 4 = 0
3x + y - 9 = 0

What is the solution set of the given system?

Answer 1

just add the equations together, this will eliminate y and allow you to solve for x.

when you have a value for x, substitute into either equation to find y

Answer 2

how would i add them together?

Answer 3

2x - y - 4 = 0
3x + y - 9 = 0
========
5x-13
x=13/5

Answer 4

Now you have x you have to solve for y

Answer 5

how?

Answer 6

would it be 6/5?

Answer 7

Put the value of x in equation no2
3x + y - 9 = 0
3(13/5)+y-9=0
and yes...y =6/5

Answer 8

oh ok thank you so much!

Answer 9

You're welcome :)
