8y-10=6y-2 help me please I don't get this

murzikaleks [220]

$8y-10=6y-2$

$8y-10=6y-2:y$ $| Solve \ for \ y|$

$8y=6y-2+10
 
$ $|Add \ 10 \ to \ both \ sides|$

$
8y=6y+8
 
$

$
8y-6y=8
 
$ $|Subtract \ 6y \ from \ both \ sides|$

$2y=8$

$y=8/2$ $|Divide \ both \ sides \ by \ 2|$

$y=4$

$\star \ Hence \ solved$
