Question 159469
It looks like the problem is: Find {{{y}}} when {{{x=6}}}
{{{2*(x - y) = 8}}}
{{{2*(6 - y) = 8}}}
divide both sides by {{{2}}}
{{{6 - y = 4}}}
subtract {{{6}}} from both sides
{{{-y = 4 - 6}}}
Multiply both sides by {{{-1}}}
{{{y = -4 + 6}}}
{{{y = 2}}} answer
check answer:
{{{2*(x - y) = 8}}}
{{{2*(6 - 2) = 8}}}
{{{2*4 = 8}}}
{{{8 = 8}}}
OK
