-6 (w - 4 ) + 8w = 2 (w + 9)
mutiply the first bracket by -6
(-6)(w)= -6w
(-6)(-4)= 24
mutiply the second bracket by 2
(2)(w)= 2w
(2)(9)= 18
-6w+24+8w= 2w+18
-6w+8w+24= 2w+18
2w+24= 2w+18
move 2w to the left side
sign changes from +2w to -2w
2w-2w+24= 2w-2w+18
0+24= 0+18
24= 18
Answer: no solution
Hi,
Let the
Youngest brothers age = x+2
Middle brothers age = x+4
Oldest brothers age = x+6
So,
Youngest brothers age = x+2 = 28+2 = 30 years of age
Middle brothers age = x+4 = 28+4 = 32 years of age
Oldest brothers age = x+6 = 28+6 = 34 years of age
Have a great day!
So it went from the 16th term to the 17th term, and went from 21 to -1... what would the "common difference"
d be then?
le'ts see
alrite.. so d = -22.. hmm what would the first term be then?
which of course, you can rewrite as
which are all the same.
