Ответ:
-2 and -1
Step-by-step explanation:
the number line has these numbers (in order):
-5 -4 -3 -2 -1 0 1 2 3
and the question asks BETWEEN which TWO numbers it is and the number is -1.5 which on the number line is a little lower than -1 and a little higher than -2 (in negative standards) so its in between -1 and -2.
I hope this helped!

Substitute x=4y+5 into the first equation
2(4y+5)-3y=5
8y+10-3y=5
Subtract both sides by 10
5y=-5
Divide both sides by 5
y=-1
Now that we have a value of y we can put that value into any equation and we will get the value of x
I will do it to both equations to prove it
2x-3(-1)=5
2x+3=5
Subtract both sides by 3
2x=2
Divide both sides by 2
x=1
x=4(-1)+5
x=1
So your final answer is x=1 and y=-1
