Answer :
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).
Answer:
We have to prove that,
-2(x+1)=8, then x= -5
L.H.S.
[tex]-2(x+1)=8[/tex]
By distributive property,
[tex]-2x-2=8[/tex]
Adding 2 both sides ( Additive property of equality )
[tex]-2x-2+2=8+2[/tex]
[tex]-2x=10[/tex]
Divide both sides by -2 ( Division property of equality ),
[tex]\frac{-2x}{-2}=\frac{10}{-2}[/tex]
[tex]x=-5[/tex]
= R. H. S
Hence, proved....
