Answer:
Step-by-step explanation:
so the equation would be 63+12x=15x
now you would have to isolate the variables
63+ 12x= 15x
-12x -12x
leaving you
63 = 3x
21=x
Hoped that helped
If this is good plz mark me as brainliest
-x^5 - 7x^4 + x^2 + (1/8)x - 9
Rewrite the given -9+1/8x-7x^4+x^2-x^5 in descending order of the variable x:
-9+1/8x
$9
If you do 13x1.50= 19.5
28.50 - 19.5 = 9
