You can put this solution on YOUR website! 6 - + = -7
you need to multiply both sides with the least common denominator (lcd) of 3 and 5 which is 15
15 . (6 - + ) = -7 . 15
90 - 5x - 3x = -105
90 - 8x = -105
now we need to have x and it's coefficient at one side and numbers in the other side.
-8x = -195
just dividing both sides with -8 will help us to find out the answer.
x = 24,375
