Alright to find the answer.
Simplify the left side.
3x÷2-15÷2=-6
Now move all the terms that are not containing x to the right side of the equation.
3x÷2=3÷2
Multiply the numerator of the first fraction by the denominator of the second fraction. Set this equal to the product of the denominator of the first fraction and the numerator of the second fraction.
(3x)⋅(2)=(2)⋅(3)
Finally, solve the equation for x which is going to equal 1
So the answer is x=1
Hope this helped you.
