Answer:

option C gives, x = 8

Explanation:

A.


(5)/(2)x+(7)/(2)=(3)/(4)x+14


(5)/(2) x-(3)/(4) x = 14-3.5


(10)/(4) x-(3)/(4) x = 10.5


(7)/(4) x = 10.5


x=(10.5*4)/(7)


x = 6

B.


(5)/(4)x-9=(3)/(2)x-12


(5)/(4)x-(3)/(2)x=-12+9


(5-6)/(4) x = -3


-x = 4(-3)


x =12

C.


(5)/(4)x-2=(3)/(2)x-4


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


(5)/(4)x-(6)/(4)x=-2


-x = (-2)*4


x=8

D.


(5)/(2) x-7 = (3)/(4)x+14


(5)/(2) x-(3)/(4)x = +14+7


(10)/(4) x-(3)/(4)x = +21


(7)/(4) x=21


x= (21*4)/(7)


x = 12
