Answer:
-0.6n+0.2p
Step-by-step explanation:
2.8n-0.9p-3.4n+1.1p
You can only add the numbers with the same variables (n,p)
2.8n-3.4n-0.9p+1.1p
= -0.6n+0.2p
55555
So you combine the like terms of 2.8n and -3.4n and then you combine the like terms of 1.1 and 0.9 and then boom!!!!

Solve for -5/6*n=40
n = 40/(-5/6)
n = 40 * -6/5
n = -48
answer n= -48
x = 256
-5/8x = -160
Multiply each side by -8/5 to isolate x
-8/5*-5/8x = -160*-8/5
