Answer:

hloo frnds

Step-by-step explanation:

2(2x+3)=2x‐8

4x+6 =2x-8

4x-2x = -8 -6

2x = -14

x= -14/2

x=-7

Therefore, x= -7

Answer 2

Question:-

Find x from the equation 2(2x + 3) = 2x – 8 is

A. -7

B. 7

C. 1

D. -1

Answer:-

• The value of x is –7.

Solution:-

$\large{ \tt : \implies \: \: \: \: 2(2x + 3) = 2x - 8}$

$\large{ \tt : \implies \: \: \: \: 4x + 6 = 2x - 8}$

$\large{ \tt : \implies \: \: \: \: 4x - 2x = - 8 - 6}$

$\large{ \tt : \implies \: \: \: \: 2x = - 14}$

$\large{ \tt : \implies \: \: \: \: x = \frac{ - 14}{ 2} }$

$\large{ \tt : \implies \: \: \: \: x = - 7}$

• The value of x is –7.

Verification :-

$\large{ \tt : \implies \: \: \: \: 2(2 \times( - 7 )+ 3) = 2 \times ( - 7) - 8}$

$\large{ \tt : \implies \: \: \: \: 2(( - 14) + 3) = - 14 - 8}$

$\large{ \tt : \implies \: \: \: \: 2 \times - 11 = - 22}$

$\large{ \tt : \implies \: \: \: \: - 22 = - 22}$

HENCE VERIFIED!!

Correct option is A
