Question

using the method of substitution how do I solve
25x+5y=11
-5x=y+10

Answer 1

From the second equation, y = -5x-10
Put that into the first equation in place of y

Answer 2

so is it25x+5(-5x-10)=11

Answer 3

\[25x+5(-5x-10)=11\]

Answer 4

\[25x-25x-50=11\]

Answer 5

\[0-50=11\]

Answer 6

\[-50=11\]

Answer 7

NO!! NOT TRUE!!! There is no solution. The lines must be parallel. Let's check the slopes and see if they are the same.

Answer 8

Sure enough. The slopes are both -5 so the lines are parallel and there is no solution.

Answer 9

well that is what I was wondering couldn't seem to get it was close thanks
