Answer 2

Answer:

Question :-

if 2x + 7 = 5, then x = ?

Required Answer :-

if 2x + 7 = 5, then x = -1

Solution :-

$2x + 7 = 5$

$2x = 5 - 7$

$2x = - 2$

$x= \frac{ - 2}{2}$

$x= \frac{ - \cancel 2}{ \cancel2}$

$x = - 1$

Verification :-

To verify your answer, let's substitute x = -1 in the given equation

$2x + 7 = 5$

$2( - 1) + 7 = 5$

$- 2 + 7 = 5$

$5 = 5$

$\bf \small \: LHS = RHS$

$\bf \small \: Hence \: verified \: !$

$\bf \small\therefore \: the \: value \: of \: x \: is \: - 2$
