Question

If 5x +7 = 3 ,then x = ?
2 2
(a) 5
(b) -5
(c) 6
(d) -6.​

Answer 1

Question -:

If 5x + 7 = 3, then find x.

$\sf\underline{Solution }\dag$

$5x + 7 = 3$

$5x = 3 - 7$

$5x = - 4$

$x = \frac{ - 4}{ \: \: \: 5}$

None of these will be the value of x.

The value of x is - 4/5.

Hope it helps! :)

Answer 2

$\Huge\rm\color{red}{answer:}$

$\large\bf{{\underline{To~find}}:}$

$\sf The \: value \: of \: \: ‘ x ’ \: \: in \: the \: equation :$

$\sf{~~~~~~5x+7=3}$

$\sf{:→ 5x=3-7}$

$\sf{:→ 5x=-4}$

$\sf{:→ x=\color{blue}{\underline{\boxed{\bf~{\dfrac{-4}{5}}~}}}}$

$\sf I \: hope \: that \: either \: the \: question \: or \: the \: options \: \: \: \: \: \\ \sf have \: gone \: wrong, \: because \: none \: of \: the \: options \: \: \: \\ \sf given ,\: becomes \: your \: answer. \: Hope \: it \: would \: help$
