Answer:
(-2, 9)
Step-by-step explanation:
1) Multiply each term of the top equation by two.
2(x) + 2(y) = 2(7)
2x + 2y = 14
2) Use elimination to get rid of the y's
2x + 2y = 14
-(5x + 2y = 8)
Translates to...
2x + 2y = 14
+ (-5x - 2y = -8)
= -3x = 6
3) Solve for x by dividing each side of the equation by -3.
x = -2
4) Plug in x to find the y-value
x + y = 7
-2 + y = 7
-2 + 2 + y = 7 + 2
y = 9
I hope this helps!
Answer:

I will help you wit what you need
Step-by-step explanation:
Range=(-40 C,125 C)
C=5/9(F-32)
-40=(5/9)(F-32)
-72=(F-32)
-40=F
125=(5/9)(F-32)
225=(F-32)
257=F
Range (F)=(-40,257)
-40<F<257
