#x=-62/3#

Explanation:

Make the denominators the same by multiplying them with each other.

#(3x(5))/(6xx5) - (6(4x+6))/(6xx5) = 5#

#(15x-24x-36)/30=5#

Multiply both equations by #30# to remove it.

#15x-24x-36=150#

#-9x=186#

#:.x=-62/3#

x = -20(2/3)

Explanation:

Taking L CM for 5, 6 as 30,
#((5*3x)-(6*(4x+6)))/30=5#

#15x-24x-36 = 150#
#-9x = 150+36 = 186#
#x = -20(2/3)#
