Answer:
There is one solution
Step-by-step explanation:
2x + y = -1
8x + 3y = -2
Multiply the first equation by -4
-8x -4y = 4
Then add the equations together to eliminate x
-8x -4y = 4
8x + 3y = -2
--------------------
-y = 2
Multiply by -1
y =-2
Now find x
2x+y =-1
2x+-2 =-1
Add 2 to each side
2x-2+2=-1+2
2x=1
Divide by 2
x = 1/2
Linear positive because you can see, it’s moving up not down.
Your answer for 15 is D or C. For 16 I’m estimating 125?
98 divided by 2 equals 49
55 divided by 5 equals 11
It looks correct to me :)
