Answer:

-0.3n + 0.6

Step-by-step explanation:

We can eliminate the parentheses, obtaining:

0.5n - 0.3 - 0.8n + 0.9

and then combine like terms, obtaining:

-0.3n + 0.6

Answer:

-0.3n + 0.6

Step-by-step explanation:

if we write out the entire expression we have:

0.5n - 0.3 - 0.8n + 0.9 (two negative signs create a positive sign)

then we add and subtract

and receive

-0.3n + 0.6

URGENT, ALL HELP ACCEPTED PLEASE!<br><br> Solve y= 3x-1 and (1/2)y+x=1 for their COMMON solution.

Simplify the second equation.

1/2y = -x + 1

Multiply both sides by 2

y = -2x + 2

Since both equations equal y you can set them equal to each other.

-2x + 2 = 3x - 1

Solve for X

-5x = -3

x = 3/5

Plug this into one of the equations.

3(3/5) - 1 = y

1.8 - 1 = y

y = .8
