Question

Solve 3(x + 3) - 2(x - 1) = 5(x - 5) and check the result.
Find xif 2p25p - 3x = -6. when p = -2.​

Answer 1

$\sf \Large Solution!!$

$\sf \to 3(x+3)-2(x-1)=5(x-5)$

$\sf \to 3x+9-2x+2=5x-25$

$\sf \to x+11=5x-25$

$\sf \to 11+25=5x-x$

$\sf \to 36=4x$

$\sf \to x=\dfrac{36}{4}=9$

$\sf \large Verification!!$

$\sf \to 3(x+3)-2(x-1)=5(x-5)$

$\sf \to 3(9+3)-2(9-1)=5(9-5)$

$\sf \to 3(12)-2(8)=5(4)$

$\sf \to 36-16=20$

$\sf \to 20=20$

$\sf LHS=RHS$

$\sf Hence,\:verified.$

______________________________

The second statement is incomplete. There isn't a sign between 2p and 25p. So, I'm not answering it. Hope you understand.
