Assuming in the second bracket, 3y is to the power of 4:
you put each power seperatly:
5y^4+(-3y^4)
-3y^3+6y^3
2y^2+(-4y^2)
-6y+-4y
5+(-8)

you get:
2y^4
3y^3
-2y^2
-10y
-2

so the answer is 2y^4+3y^3-2y^2-10y-2

5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x
arlik [135]

Answer:

-3

Step-by-step explanation:

We need to use the distributive property a couple times to expand the parentheses.

Remember that when expanding parentheses, we find the sum of the products of the outside term with each of the inside terms.

5(x - 4) = 5 * x + 5 * (-4) = 5x - 20

-(2x + 5) = -1 * 2x + -1 * 5 = -2x - 5

Now we have:

5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

Combine all the terms with x:

-x - 20 = 6x + 1

7x = -21

Divide by 7:

x = -21/7 = -3

The answer is thus -3.
