Solve the following rational expressions.
#1 (4y3)/8 + (3)/(4y) = (y+3)/2
#2 5/(2x1) = 1  (8x16)/(10x5)

in each case find the LCD , then multiply each term by that.
I will do the #2
5/(2x1) = 1  (8x16)/(10x5)
5/(2x1) = 1  (8x16)/(5(2x1) )
LCD = 5(2x1)
5/(2x1)*5(2x1) = 1*5(2x1)  (8x16)/(5(2x1) )*5(2x1)
25 = 10x  5  (8x16)
14 = 2x
x = 7
