Solve the following proportion:

[tex]\[ \frac{p-5}{p+1} = \frac{2}{3} \][/tex]

A. [tex]\( p = 3 \)[/tex]
B. [tex]\( p = 17 \)[/tex]
C. [tex]\( p = 13 \)[/tex]
D. [tex]\( p = -13 \)[/tex]



Answer :

Sure, let's solve the given proportion step-by-step:

The proportion given is:
[tex]\[ \frac{p-5}{p+1} = \frac{2}{3} \][/tex]

To solve for [tex]\( p \)[/tex], we will use cross-multiplication. Cross-multiplication involves multiplying each side of the equation by the denominators of the other side. This gives us:
[tex]\[ 3(p-5) = 2(p+1) \][/tex]

Next, distribute the numbers on both sides:
[tex]\[ 3p - 15 = 2p + 2 \][/tex]

Now, we need to get all the terms containing [tex]\( p \)[/tex] on one side and the constant terms on the other side. Subtract [tex]\( 2p \)[/tex] from both sides:
[tex]\[ 3p - 2p - 15 = 2 \][/tex]
[tex]\[ p - 15 = 2 \][/tex]

To isolate [tex]\( p \)[/tex], add 15 to both sides of the equation:
[tex]\[ p = 2 + 15 \][/tex]
[tex]\[ p = 17 \][/tex]

So, the solution to the equation is:
[tex]\[ p = 17 \][/tex]

Thus, from the given options, the correct value for [tex]\( p \)[/tex] is:
[tex]\[ \boxed{17} \][/tex]
