Question

solve by transposition and verify 2x-1=3x+7​

Answer 1

2x-3x=7+1

-1x=8

x=8/-1

x=-8

Answer 2

$\huge\tt\colorbox{pink}{Answer}$

$2x - 1 = 3x + 7$

$2x - 3x = 7 + 1$

$- x = 8$

$x = - 8$

L.H.S

$= 2x - 1$

$= 2( - 8) - 1$

$= - 16 - 1$

$= - 17$

R.H.S

$= 3x + 7$

$= 3( - 8) + 7$

$= - 24 + 7$

$= - 17$

Hence L.H.S. = R.H.S.
