8x-9y=11
First you move the 8x because you have to leave the 9y alone
8x-9y=11
-8x -8x
-9y=11-8x
Now you have to move the -9, so the inverse of multiplying is dividing so you divide -9.
-9y/-9= 11/-9 -8x/-9
since you can't have negative as a denominator it would be:
y= -11/9+8x/9

Answer:
b
Step-by-step explanation:
5x +3(x-1) -10x -2x -3
5x +3x -3 -10x -2x -3
8x -3 -10x -2x -3
-2x -3 -2x -3
-4x -6
if this equation is equal to zero then x = -3/2
It would be 3.9 x 10^4
