1%2F%28x-1%29+%2B+3+=+4%2F%28x-1%29
multiply both sides by x-1
1+%2B+3%28x+-+1%29+=+4
subtract 1 from both sides
3%28x+-+1%29+=+3
3x+-+3+=+3
add 3 to both sides
3x+=+6
x+=+2 answer
check answer
1%2F%28x-1%29+%2B+3+=+4%2F%28x-1%29
1%2F%282-1%29+%2B+3+=+4%2F%282-1%29
1%2F1+%2B+3+=+4%2F1
1+%2B+3+=+4
4+=+4
OK
