(x-5)(x-6) so x=5,6
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9

-14 + c + 6 = -5-14 + c = -5 minus 6-14 + c = -11c = -11 minus -14c = -11 plus 14c = 3

well unless its some super-hard math I've never heard of, you change the two minus signs next to each other in to plus signs and go from there. 5+5+6=16 you know, you should be able to figure that out! - + - = + sorry that looks confusing. a minus plus a minus equals a plus! hope this helps!!
11 - 5 = 6
A equals 4 because 4 plus 6 is 10 or 10 minus 6 is 4.
