Use elimination to solve this system of equations. X-4y=-11 and 5x-7y=-10

1 answer:

4 0

X-4y=-11<=> -5x + 20y = 55
 5x - 7y = -10
=>0*x + 13*y = 45 => y =45/13 => x = 4*(45/13) -11 = 180/13 -11 =>
x = 37/13;

I think the answer would be C

As it is basically a straight line so there wouldn't be necessary for there to be a scatter diagram for it.

I may be wrong so take it with a grain of salt

Answer:

Infintely many solutions

Step-by-step explanation:

I'm going to assume that the capital y is equal to the lowerase y

if you subtract y and two from both sides in the second equation you get

-y=2x-2

you then divide by -1 to get it into a normal form

y= -2x+2

this is the same as the first equation, these lines are the same
