#x=111/16#

Explanation:

#3(x-1)-2x-3+15={4x-1}/3+x+1/12#

#3x-3-2x-3+15={4x-1}/3+x+1/12#

#x+9={4x-1}/3+x+1/12#

#9={4x-1}/3+1/12#

#108=16x-4+1#

#16x=111#

#x=111/16#

The answer is #x = 111/16#

Explanation:

We have the question

#3(x-1) - 2x -3 + 15 = "4x-1"/3 + x + 1/12#

Removing the parentheses,

We get,

#3x-3 - 2x -3 + 15 = "4x-1"/3 + x + 1/12#

From addition and subtraction of 'similar' terms. We get,

#x+9 = "7x-1"/3 +1/12#

Now separating keeping similar terms in one side. We have,

#9 - 1/12 = "7x-1"/3 - x#

(Note: The change in sign occurs due to the shifting of term from one side to the other)

Now by simplifying,

#107/12 = "4x-1"/3#

Multiplying both sides by 12. We get,

#107/12 * 12 = "4x-1"/3 * 12#

or #107 = 16x -4 #

Adding 4 to both sides. We get,

or #107 +4 = 16x -4 +4 #

or #111 = 16x #

Now dividing both sides by 16. We get,

or #111/16 = "16x"/16 #

Thus, Giving

#x = 111/16#
