Answer:

-44x⁸–8x⁷–36x⁶–4x⁵

Step-by-step explanation:

when you expand problems like these you need to multiple the number in front of the variable the the other numbers in front of the variables and add the exponents
like this
-4•11= -44 | 5+3=8 I -44x⁸
-4•2= -8 | 2+5=7 | -8x⁷
-4•9= -36 | 1+5=6 | -36x⁶
-4•1= -4 | 0+5=5 | -4x⁵
put it all together and you get -44x⁸–8x⁷–36x⁶–4x⁵

if my explanation is confusing I'm sorry feel free to ask questions

Answer:

4x + 8y = 17

Solve for y.

You want to get y on one side of the equal sign by itself so... you subtract 4x from both sides to get:

8y = -4x + 17

Then you divide both sides by 8 to get:

y= -4x/8 +17/8

Then simplify the fractions to get:
