Question

how do I solve 2x-8y=15, -6x+24y=15

Answer 1

system of equations

Answer 2

2x-8y=15 (mutiply by 3)
-6x+24y=15

6x-24y=45
-6x+24y=15
==========
-6 +6 will be cancelled
-24 +24 will be cancelled

No solution

Answer 3

So I multiply just the two by 3?

Answer 4

Noo the whole first eq

Answer 5

okay so I write it like this 2x*3-8y*3=15
6x-24y=15
but when i subtracted the 6 from the 24 i came up with 18

Answer 6

we multiply 15 with 3 aswell

Answer 7

and why are you subracting 6 from 24...we add first eq and second eq

Answer 8

this has no solution anyway
