Question 566339
substitute the 6 in for x.. this makes {{{ 2(x-y)= 8 }}} into {{{ 2(6-y)=8 }}}. now use distributive property and multiply your 2 by everything in (). {{{ 12-2y= 8 }}} then subtract 12 from both sides of the equation (12-2y) -12 and 8-12. giving you {{{ -2y= -4 }}} then divide by -2... y = 2
