Answer:
m = 
Step-by-step explanation:
distribute parenthesis on both sides
ac + am = 2c + 6m ( collect terms in m on left side )
subtract 6m from both sides
ac + am - 6m = 2c ( subtract ac from both sides )
am - 6m = 2c - ac ( factor left side )
m(a - 6) = 2c - ac ( divide both sides by (a - 6))
m =
So 8x+4+4x+8=15x-9
Combine like terms.
12x+12=15x-9
Add 9 to both sides.
12x+21=15x
Subtract 12 from both sides.
21=3x
Divide both sides by 3.
x=7
Now plug in 7 for x in 8x+4.
8(7)+4
56+4
=60
Answer:
205
Step-by-step explanation:
Were gonna start by writing an equation (121+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 205. Hope this helps.
