Question 56443
please isolate the variable x for each of the problems and so the steps involved

1.  
{{{(1/3)x+(3/4)y=5}}}
{{{(1/3)x+(3/4)y-(3/4)y=-(3/4)y+5}}}
{{{(1/3)x=-(3/4)y+5}}}
{{{3(1/3)x=3(-(3/4)y+5)}}}
{{{(3/3)x=3(-3/4)y+3(5)}}}
{{{1x=-(9/4)y+15}}}
{{{highlight(x=-(9/4)y+15)}}}
Happy Calculating!!!
