I need help with this algebra problem?

Question

Okay.I have to simplify this expression: (5p - 6r) - (p + r)
Can someone please give me the answers or show me how to do this problem?I'm stuck.

Answer 1

ok i will help you

(5p - 6r) - (p + r)

5p-6r-p-r
4p-7r

Answer 2

Just add or subtract the number of p and the number of r that are in the expression. The only thing that keeps it from being very simple is that you have to watch what happens when you subtract a term with a minus sign.

Working on p first there is 5p from the first parenthesis and -p from the second. When you add them you have (6-1)x p so there is 4p left.

Working on r next there is -6r from the first parenthesis and - (-r) from the second. When you add them you have (-6--1)x r so that becomes (-6+1)x r which is -5r

You end up with 4p-5r

Answer 3

open the parenthasis
(5p-6r) - (p+r) = 5p-6r-p-r when you open a() that has a - sign
, terms inside change the signs too.

=5p-p -6r-r
=4p-7r answer.

When you poen the () , you multiply each term inside the() with the number and the sign outside the (),

In this case both () had 1 outside it. the first() had + sign and second() had -1 outside it.

Answer 4

(5p-6r)-(p+r)
basically, the -sign gets distributed (multiplicatively) over the addition in (p+r) so we get: -(p+r)= -p-r

so the problem becomes:
=(5p-6r)-p-r now lose the brackets:
=5p-6r-p-r take the p's and r's together:
=p(5-1) +r(-6-1)
=4p-7r.

I hope i haven't made it more complicated in the attempt to explain.

Answer 5

(5p-6r)-(p+r)
=5p-6r-p-r(remove the brackets and multiply - sign)
=4p-7r

Answer 6

hi. first distribute the -1.
(5p - 6r) + (-1)*(p + r) = (5p-6r)-p-r = 5p-6r-p-r = 4p-7r

Answer 7

(5p - 6r) - (p + r)
= 5p -p -6r-r
=4p-7r

Answer 8

ok heres the anwser 4p-5r
u gonna have to figure out how i did it and if its right
( but i think its right)
