log+%282x%29+-+log%289%29+=+1+
log%282%29%2Blog%28x%29-log%289%29+=+1+.......since log%2810%29+=+1, we have
log%28%28x%29%29+=+log%2810%29%2Blog%289%29-log%282%29+
log%28%28x%29%29+=+log%28%2810%2A9%29%2F2%29+
log%28%28x%29%29+=+log%28%285%2A9%29%29+
log%28%28x%29%29+=+log%28%2845%29%29+
x+=+45+

There's no bases. 


log 2x - log 9 = 1

log+%282x%2F9%29+=+1 ------ Logarithmic form

2x%2F9+=+10%5E1 ------- Logarithmic form

2x%2F9+=+10

2x = 90 -------- Cross-multiplying

x+=+90%2F2, or highlight_green%2845%29
