Find coordinates for x+5y=10 and 3x+5y=0. I need to know how to do this plz explain.

There are several ways you can do this, but one of the best ways is to use a graphing coordinate calendar. The most popular one is Desmos Graphing Calculator. I've attached an image of my work below using the system.

Answer

As you can see, both equations intersect at a certain coordinate point. This coordinate point is the point you need for the answer. The intersection is (-5,3).

I hope this helps. If you have any more questions, please feel free to post them and someone will be able to help you, whether it's myself or others. Please leave a like, rating, and if possible, Brainliest. Have a great day!

Answer:

x = -5

y = 3

Step-by-step explanation:

x+5y=10.........i

3x+5y=0........ii

From (i)

x = 10-5y.....iii

Substitute (iii) in equ(ii)

3(10-5y) + 5y =0

Expand the bracket

30 - 15y + 5y = 0

30 - 10y = 0

30 = 10y

30/10 = y

3 = y......(iv)

Substitute 3 for y in the first equation..

x+5y=10

x + (5×3) = 10

x = 10 - 15

= -5

x = -5 and y = 3
