Question

Solve the system of equations by elimination:
12x-10y=0
-6x+5y=2

Answer 1

again, there is no solution

Answer 2

Why?
or How

Answer 3

u end up with 4=0

Answer 4

notice the slope. they are the same

Answer 5

Will you show me the work please?

Answer 6

12x-10y =0
can be re rewritten as (dividing by 2 on both sides)
6x-5y = 0 (multiply by -1 on both sides)
or -6x+5y = 0

Answer 7

so your two equations are
-6x+5y =0 ------>1
-6x+5y =2 ------->2
subtract 2 from 1
0 =-2
this is nonsensical
so this has no solution.

Answer 8

Thanks

Answer 9

What about 4x-6y=20
2x-3y=10

Answer 10

this = 0?

Answer 11

they are the same line. they have infinitely many solutions

Answer 12

So? what do i write

Answer 13

infinitely many solutions

Answer 14

6x-5y=0 --- 6x=5y --- x=5y/6
-6x+5y=2 -- (-6(5y/6)) + 5y =2 --- -5y +5y=2 --- 0=2
