Greetings!

"Solving equation: $6x+7=8x-13$ ?"...

Solve for x.
$6x+7=8x-13$
Add 13 to both sides.
$(6x+7)+13=(8x-13)+13$
Simplify
$6x+20=8x$
Subtract both sides by 6x.
$(6x+20)-6x=(8x)-6x$
Simplify.
$20=2x$
Divide both sides by 2.
$(20)/2=(2x)/2$
Simplify.
$10=x$

The answer would be 10.

Hope this helps.
