​

Answer 1

Answer:

5x + 3 = 7x - 1

now collect like terms

3 + 1 = 7x - 5x

every time you move something it changes signs

4 = 2x anything multiplied is divided on the other side and vice versa

4/2 = x

2 = x

Given :-

$\sf\bullet { 5x+3=7x-1 }$

To find :-

$\sf\bullet {Value \: of\: x}$

$\huge{ \underline{ \pink{ \mathfrak{Solution}}}}$

$\tt{\orange{5x+3\: =\:7x-1 }}$

$\tt{\orange{\: \: \: \: -2x \:=\: -4}}$

$\tt{\orange{\: \: \: \: \: \: \: \: \: \: x \:=\: 2 }}$

$\therefore{ \purple{ \mathrm{ \large{ \underline{ \underline{So\:option\:d\:is\: correct}}}}}}$
