Answer:
(- 1)/(11)

Explanation:

Note: the "." symbol stands for multiplication

Given,


(2x+4)/(3) \\ -
(5x-7)/(2) = 5

First we the LCM = 6,


(2(2x+4))/(2.3) -
(3(5x-7))/(3.2)= 5

Then, we join both sides, since they have same denominator


(2(2x+4) - 3(5x-7))/(6) = 5

Multiply again


(4x+8 - 15x+21)/(6) = 5

Add the same numbers


(-11x + 29)/(6) = 5

Transpose 6 to the other side

-11x + 29 = 5.6

-11x + 29 = 30

Transpose 29 to the other side

-11x = 30 -29

-11x = 1

Transpose 11 to the other side to get answer

x =
(-1)/(11)
