Question 69895: Would you happen to know how to do a question for instance (4x-5y)-(6x+3y)-(7x+2y)? I got the answer of -9x-10y. I wanna know if you know how to do the solution and how I get the - in front of the numbers. If you can help me it would be greatly appriciated. Answer by ptaylor(2198) (Show Source):
You can put this solution on YOUR website!
Note that -(6x+3y), for example, is the same as -1 times (6x+3y) which
equals (-1)*(+6x) +(-1)*(+3y) and this equals -6x-3y
Remember: plus times minus equals minus and vice versa
(4x-5y)-(6x+3y)-(7x+2y) We will get rid of the parens
4x-5y-6x-3y-7x-2y collect like terms
-9x-10y
