First because 5x+5y=0 you can factor the 5 from equation so:
5(x+y)=5(0) => x+y=0
and by solving for x using elimination method
-8x+y=36
x+y=0
by subtracting both x and y we get
-9x=36 => x=-4
by inputing x into the "x+y=0" equation we get:
-4+y=0 => y=4

Which of the following values are solutions to the inequality 1 + 5x < 4?
Romashka-Z-Leto [24]

Step-by-step explanation:

you cant add 1 to 5x, so subtract 1 on both sides leaving you with 1 + 5x < 4 that equals 5x < 3 -1 -1

then divide 5 from both sides 5x < 3 This leaves 5 5

you with x < 3/5
