Question

please find the value of x that is given with the attachment.​

Answer 1

Answer:

Step-by-step explanation:

(x+1)(2x+5) - 2x²-5 = 3(x-2)

2x²+5x+2x+5-2x²-5 = 3x-6

5x=3x-6

2x= -6

x = -3

Answer 2

Answer:

Step-by-step explanation:

(x+1)x(2x+5) = 2x2 + 5x + 2x+ 5

=> 2x2 + 5x + 2x + 5 -2x2 - 5x

= 7x -----------------> 1

3(x-2) = 3x-6 _____________>

equation 1 and 2

=> 7x= 3x - 6

=> 7x - 3x = -6

=> 4x = -6

=> x=-6/4

Hence proved.....
