Seeing where the x and y diffreant on the line :)
<u><em>Answer:</em></u>
- 84x - 70
<em><u>Step-by-step explanation:</u></em>
We want to combine like terms:
-10 - 90x + 6x - 60
We can see (-10) and (-60) are both regular constants so:
- 10 - 60 = - 70
Then (-90x) and (+ 6x):
6x - 90x = - 84x
- 84x - 70
Surface area = 
= 
x 3.14 x 3 x 3 x 3 = 3.14 x 4 x 3 x 3 = 113.04 yd^2 = approx. 113.1 yd^2
Well depending on the equation you look at both sides and eliminate everything from both using addition, subtraction, multiplication, and division.
Ex:
3c-4=7 first add the 4 because you use the opposite type of operation so you add it to 7 which gives you:
3c=11 next you have to divide to get it alone
3c/3=11/3
which gives you
c= 3.66666666667
