3x-6y=9<br> x=2y+3<br><br> SOMEONE HELP ME SOLVE THIS STEP BY STEP TY
RideAnS [48]

Answer:

0=0

infinitely many solutions

Step-by-step explanation:

plug x=2y+3 as x into 3x-6y=9...so

3(2y+3)-6y=9, which has our x=2y+3 plugged in because that is what x equals

if you solve its

6y+9-6y=9

0y=0

y=0

making it 0=0

you can't go further from this
