Question

Please Answer This, with A, B, C, or D. and explain why it is so i can try and understand it. :D

Answer 1

B. (5q - 12) / 12

Explanation:

7p + 5q = 19p + 12

So, we are looking for p, let's move all the p on the left, and the rest on the right

7p + 5q = 19p + 12

7p - 19p = 12 - 5q

-12p = 12 - 5q

Now to get single p we need to divide both sides by -12

-12p = 12 - 5q

p =
`(12 - 5q)/(-12)`

We don't have answer like this, so we have to get rid of the minus from this equation. To do so, we have to multiply the fraction's top and bottom by (-1)

`(12 - 5q)/(-12) * (-1)/(-1) = (- 12 + 5q)/(12)`

all right, we almost got it, now let's change the order in top of the fraction:

p =
`(- 12 + 5q)/(12)`

p =
`(5q - 12)/(12)`

And it's done

Answer 2

b

Explanation:

1. first u have to put the like terms together which are 7p and 19p
2. when u move the 19p th 7p it turns to minus su have to minus 7p-19p
3. which equals to -12
4. check if there is more like terms there arent so u have to keep the rest the same
