(3 − 6n5 − 8n4) − (−6n4 − 3n − 8n5)

2n^5−8n^4+3n+67

Step-by-step explanation:

Simplify the expression.

2n⁵−2n⁴+3n+3

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
