Answer:
it looks like it would just be -1
Step-by-step explanation:
there two -x and two positive x which would cancel out. three positive 1 and four negative 1. -4+3= -1
that's the best I could come up with
Answer:

Step-by-step explanation:
simplify

to

then
-0.05 × 120 = -6
then we have our answer
-6√2
Answer:
(1, -1)
Step-by-step explanation:
we isolate y in the first equation
2x+y=1
-2x. -2x
y=1-2x
and now we fill y into second equation
4x-2(1-2x)=6
4x-2+4x=6
8x-2=6
+2 +2
8x=8
/8 /8
x=1
and now to find y we insert x
2(1)+y=1
2+y=1
-2. -2
y= -1
hopes this helps
The value of x if that's what you mean is 2 because first you add 3 from both sides and your new equation should be 2x>14-5×, then you add 5x from both sides and your new equation should be 7x>14. After that you divide 14 by 7 and your final answer will be x=2 or 2
