First you'd substitute x= y-3 in the first equation.
10(y-3) -10y= 1
10y - 30 -10y= 1
The y's cancel each other out, so you're left with -30= 1. That means there's no solution :)
The domain is (-5,4). If that makes any sense, if it doesnt ill explain
Answer:
x=4 y=7
Step-by-step explanation:
When multiplying 3x by -2, you get -6x. -6x and 6x cross out. You're left with -2y=-2 and -2y=10.
Answer:
