Answer:
-2
Step-by-step explanation:
To solve you need to replace the variables with their numbers.
3(-1) - (-1^2)
-1 x -1 = -1
3 x (-1) = -3
-3 - (-1) =
-2
The number half of 25 is 12.5.
X-6y=32 Eqn(1)
X-4y=24. Eqn(2)
From eqn(1)
X=32+6y. Eqn(3)
Put Eqn 3 to Eqn 2
(32+6y)-4y=24
32+6y-4y=24
32+2y=24
2y=24-32
Y=-8/2
Y =-4
Put y into Eqn 3
X=32+6y
X=32+6(-4)
X=32-24
X=8
0.08 is the answer because it was easy to do and it was good
