Question 1086490
{{{(x+3)/(4x+1)=3/5}}}

{{{3(4x+1)=5(x+3)}}}

{{{12x+3=5x+15}}}

{{{7x+3=15}}}

{{{7x=12}}}

{{{highlight(x=12/7)}}} Check:

{{{(12/7+3)/4(12/7)+1=3/5}}}

{{{(12/7+21/7)/(48/7+7/7)=3/5}}} Tutor @MathHelper1 made a mistake as by writing 6/5 instead of 3/5.

{{{(33/7)/(55/7)=3/5}}}

{{{33/55=3/5}}}

{{{highlight(3/5=3/5)}}}
