Question

please help

2x+5y=-24
3x-5y=14

at what 2 points do thease lines intersect

Answer 1

set them equal to each other..

Answer 2

sorry meant solve both for y and x

Answer 3

2x + 5y = -24
2x = -24 - 5y
x = -12 - (5/2)y

Answer 4

plug that value into the previous one..

Answer 5

3(-12 - (5/2)y) - 5y = 14

Answer 6

then do disributive propertys right

Answer 7

The easiest approach to this kind of problem is to solve each equation for y. You should be able to do that. Then set the two non-y halves equal to each other.

Example: y = 2x + 1 and y = 3x - 5
Set 2x + 1 = 3x - 5
Solve for x.
Finally, plug the x into either of the y equations to get y. Done.
