Answer:
Cube
X =8.25
Step-by-step explanation:
Answer:
x=-2, y=5. (-2, 5).
Step-by-step explanation:
15x-4y=-50
3x-2y=-16
---------------
15x-4y=-50
-5(3x-2y)=-5(-16)
------------------------
15x-4y=-50
-15x+10y=80
-------------------
6y=30
y=30/6
y=5
3x-2(5)=-16
3x-10=-16
3x=-16+10
3x=-6
x=-6/3
x=-2

Answer:
It is D.
Step-by-step explanation:
x ≤ 3 or x ≥ –1
The system is comprised of two processes
that go on at the same time:
#1). Do what ever you want to, to get 'x'
on one side of the equation, and
everything else on the other side.
#2). Whatever you do to one side of the equation,
you must immediately do the same thing to the
other side.
That's the system.
Here's how it works: (I can't believe you're in high school math
and you've never seen, studied, or practiced this before.)
You said that 4x - 9 = 2x + 15
and you need to find
what 'x' is.
Subtract 2x from each side: 2x - 9 = 15
Add 9 to each side: 2x = 24
Divide each side by 2 : x = 12 .
