-14=-13x
1.08~x
He gained 8 lbs (pounds ) and lb is like 16 and there is 16 oz (ounces ) in a pound so 128 divided by 16 = 8
The answer is:
x=-8
Because:
If you pick a number(-8) to fill in the equation written below
5x+20+5x=5x-20
After applying the -8 to x you get
-40+20-40=-40-20
When you simply the both sides you get
-60=-60
And that’s right -60 is equal to -60!
The first choice because it’s easier than having to add a bunch of numbers so S=(9)(2)(4)
