Good luck! I’d appreciate if you made this the brainliest answer! :)
Integers include negatives and decimals
whole numbers only inlcude counting numbers and 0
integers:2/3, 0.33333333, 94.345345345345..., -99
whole:0,1,2,3,4,5,6,7,8,9....
Set both y’s equal to each other.
2x-1 = 3x+4
2x-3x = 4-(-1)
-x = 5
x = -5
Plug x = -5 into any of the given equation. I will use the first one as an example.
y = 2x-1
y = 2(-5)-1
y = -11
Answer: (-5, -11)
