-5(x + 3) - 4x = 6(2x + 3) - 12
After distributing and combining like terms, this problem should read:
-9x + 3 = 12x - 9
-9x - 15 = 12x + 6
-6x = 15x - 12
-9x - 15 = 8x - 3

hi dear Kitkat;
Part a ;
-5(x + 3) - 4x = 6(2x + 3) - 12
[ (-5*x) + (-5*3) - 4x ] = [(6* 2x) + (6*3) - 12 ]
[ -5x - 15 - 4x ] = [ 12x +18 - 12]
[ -9x - 15 ] = [ 12x +6]
-9x - 15 = 12x +6
Part b ;
it is the way you should read after simplifying ;
-9x - 15 = 12x +6
Good Luck Darling.

nah u don't have it right - the answer will be x=-1
-9x-15=12x+6
-9x-12x=6+15
-21x=21
x=-1

you should bypass to a public college for help. Get help from the fewer than-paid, over-qualified people who're there and paid to assist scholars for loose. they'll show you what to do. it is not available over Y!A. i'm curious to renowned (in a rhetorical-question variety of way:) Why not bypass to a school the place the staff/instructors have the time and materials to assist? **yet God-bless your soul for the time it ought to have taken to go into those problems into your laptop!! It ought to have taken continuously! i in my view choose i ought to help.
