Answer:
We have to prove that,
-2(x+1)=8, then x= -5
L.H.S.
By distributive property,
Adding 2 both sides ( Additive property of equality )
Divide both sides by -2 ( Division property of equality ),
= R. H. S
Hence, proved....
Step-by-step explanation:
distribute the -2 to (x+1) you end up with -2x-2=8 (multiplication property). Add 2 to both sides to get rid of the -2 of the left (addition property). 8+2=10. -2x=10 divide the -2 to both sides. x=-5 (division property).
187. 5
If 2h=75km
Then 5h=?(if more, Less divide)
5÷2×75km =187.5km
