Question 81187
{{{3/4x+2/5=1}}}
Remember back when you had to add fractions and find the LCD. The worse case was always to multiply the 2 denominators to find a common denominsator. Use that same thinking here. In this case, the LCD is 20x. Rewriting the problem in terms of the LCD, you get:
{{{(15+8x)/20x=1}}}
Solve for x:
{{{15+8x=20x}}} 
{{{12x=15}}}
{{{highlight(x=5/4)}}}
Good Luck,
