Answer:
x = -4, y = -6
Step-by-step explanation:
-x+2y = -8
3x-y = -6
x = 2y+8
3(2y+8) - y = -6
6y + 24 -y = -6
5y = -30
y = -6
x = 2(-6)+8 = -12+8 = -4
x = -4, y = -6
Answer:
Ok ok, I see. So the answer is -9.
Step-by-step explanation:
We know the expresion is:
-3(-2+5)
We need to distrubute the -3 to what is in the parthese.
When I say distribute, basically you need to multiply the numbers inside the parethese by -3. So we can think of it as:
-3*-2=6
and:
-3*5=-15
Which we can rewrite as:
(6-15)
Subtract 15 from 6 and you get -9:
6-15=-9
