First you need to get rid of the parenthesis by distributing the 0.6 to each term inside.
(0.6)(10n) + (0.6)(25) =10+5n
6n +15 = 10+5n subtract the 5n on both sides and subtract 15 from both sides
6n-5n = 10-15
n=-5
Answer:
1 y=-1/10x
2 y=-x-8
3 y= 7/3x or 2 1/3x
Step-by-step explanation:
1 -x=10y
divide -x and 10 by 10
2 y+8=-x
subtract 8
3 -4+7x+4=3y
divide everything by 3
