please solve this sum by step by step​ and i will mark as brainlist​

Answer 1

Answer:

p=5

Step-by-step explanation:

For infinitely many solutions - a1/a2=b1/b2=c1/c2

IN THIS CASE

Answer 2

✒

What value of P will be following pair of linear equations have infinite solutions2x-3y=7

(p+1)x+(1-2p)y=(5p-4)

$\mathcal{\huge{\underline{\underline {\green{Answer:-}}}}}$

☑ The value of p is 5.

$\mathcal{\huge{\underline{\underline {\pink{Solution:-}}}}}$

Given , 2x-3y = 7 ______ (1)

(p+1) x + (1-2p) y = 5k - 4 ______ (2)

Here a1 =2,b1 =−3,c1 =7

a2 =p+1,b 2 =1−2p,c3 =5k−4

Since equations (1) and (2) have infinite solutions

$= \frac{a1}{a2} = \frac{b1}{b2} = \frac{c1}{c2}$

$= \frac{2}{p + 1} = \frac{ - 3}{1 - 2p} = \frac{7}{5p - 4}$

$so \: \frac{2}{p + 1} = \frac{3}{1 - 2p}$

⇒2(1−2p)=−3(p+1)

⇒2−4p=−3p−3

⇒2+3=−3p+4p

⇒p=5
