Question 63093
1. {{{ x-10 = 1x/2 }}}
add 10 tp both sides
{{{ x = 1x/2 + 10 }}}
subtract 1/2 x from both sides
{{{ 1x/2 = 10 }}}
multiply by 2
{{{ x = 20 }}}
He is currently 20


2. {{{ x+8 = (4/3)(x-6) }}}
Distribute
{{{ x + 8 = (4x-24)/3 }}}
Multiply by 3
{{{ 3x + 24 = 4x - 24 }}}
add 24 to both sides
{{{ 3x + 48 = 4x }}}
subtract 3x from both sides
{{{ 48 = x }}}
He is currently 48
