Question

Given that 5−3x=Px+R, in order to create an equation with no solutions, when R=7, then P= [blank]

Enter the value that correctly fills in the blank, like this: 42

Answer 1

x= -22.5

Explanation:

5–3x=Px + R

r= 7

P= 42

5–3x =42x + 7

-3x -42x = 7- 5

-45x =2

x= -22.5

Answer 2

p=-3

Explanation:

5-3x = Px +7

-7 from both sides

-2-3x=Px+7

add 3x to both sides

-2=Px+3x

P =-3 because it will get rid of variable
