Answer:

2x -3=7

2x=10

x=5.......

Answer 2

Answer:

$2 x - 3 = 7 \quad : \quad x = 5$

Step-by-step explanation:

$2 x - 3 = 7$

$\mathrm{ A d d \: } 3 \mathrm{ \: t o \: b o t h \: s i d e s }$

$2 x - 3 + 3 = 7 + 3$

$\mathrm{ S i m p l i f y }$

$2 x = 1 0$

$\mathrm{ D i v i d e \: b o t h \: s i d e s \: b y \: } 2$

$\dfrac{ 2 x }{ 2 } = \dfrac{ 1 0 }{ 2 }$

$\mathrm{ S i m p l i f y }$

$x = 5$
