Can you help me
Answer:19
I am not getting it​

Answer 1

Answer:

See, first do cross multiplication

Step-by-step explanation:

(X+3)(2x+1)=(x+7)(2x-5)

2x^2+x+6x+3=2x^2-5x+14x-35

2x-2x+x+6x+3+5x-14x+35=0(on transporting)

7x-9x+38=0

-2x=-38

X= 38/2

X= 19

For this to understand you must know the rules of transportation of numbers from lhs to rhs and vice versa and changing of their signs...
