HI,
If I am understanding your question properly
.
%281-y%29%2F%281%2By%29+=+%28+2%2F3%29
.
Solve by cross multiplying
3%2A%281-y%29=+2%2A%281%2By%29+
.
Simplify and Solve:
3-3%2Ay%29+=+2%2B+2%2Ay%29+
.
3-3%2Ay%29+=+2+%2B+2%2Ay%29
.
1+=5%2Ay%29
%281%2F5%29+=+y%29
y+=highlight%281%2F5%29
.
check your answer by substituting x= 1/5 into the original equation
%284%2F5%29%2F%286%2F5%29+=+%284%2F6%29+=+%282%2F3%29
