Question

Help me answer this question in the picture :)))

Answer 1

4(px + 1) = 64
The value of x in terms with p is: 3.
The value of x when p is -5 is: -3

Explanation: 64 divided by 4 equals to 16. So whatever p and x are has to equal to 15 (because there’s a +1). So it’s naturally be 5 times 3 which is 15. P standing for 5 and x standing for 3. The first one just asks what x is, and it’s 3. And the second one asks what x would be if it was -5 instead of 5. So naturally it would be -3 because a negative times a negative is a positive and the answer we have is a positive. The first answer is 3 and the second is -3.

Answer 2

x = 15p

-75

Step-by-step explanation:

remove brackets:

4px + 4 = 64

solving for x --> 4px = 64 - 4 then--> 4px = 60

then diving both sides by 4p --> x = 60\4p --> x = 15p

now solving for x when p is -5

we will substitute the -5 in the equation we got --> x= 15 (-5)

which will give us --> x = -75
