How do i do this sum?

Question

how do i do this and what is the answer please

4p+2q+3p-5q

thank u

Answer 1

Collect like terms first, eg separate the p's and q's

7p, then plus 2 minus 5q = -3q

Ans 7p-3q

Answer 2

7p -3q

Answer 3

4p+2q+3p-5q

To solve this expression, you would have to group all the like terms together(meaning the same letters together). After which you will get something looking like this:  4p+3p+2q-5q

Next, solve each variable individually.(meaning solve the p's and q's separately.Just do basic addition and subtraction within each variable than you will get  7p   &   -3q.

put this two numbers together and that is the answer.which is 7p-3q   or   -3q+7p

Answer: 7p-3q  or -3q+7p

Answer 4

Right ok. You can only add 'like' objects together. Let's use the same equation but with food.

4pears+2quiche+3pears-5quiche= 7pears and 3quiches

Now lets use the original sum.

4p+2q+3p-5q= 7p+3q

I hope you understand this.

Answer 5

since p nd q are da only two variables see if u ve similar variables in da  equation..now there r 2 of dem for p nd 2 of dem for q so add or substract ie do as instructed...

4p+3p+2q-5q

=5p-3q

Answer 6

  4p + 3p = 7p

+2q - 5q = - 3q

Answer = 7p - 3q

Answer 7

7p-3q.

Answer 8

7p - 3q

Answer 9

Hey guys how is this guy going to improve his Maths if we re doing even really easy sums for him.

Answer 10

Answer: 7p - 3q

How:

Add "like" terms, i.e.,

4p + 2q + 3p - 5q = 4p + 3p + 2q - 5q

= (4 + 3)p + (2 - 5)q = 7p - 3q

Answer 11

4p+2q+3p-5q

(add numbers with similar letters)

=7p - 3q

Answer 12

you have to add all the p's up to make 7p

then add 2q onto -5q making -3q

so then the answer is 7p-3q   =D
