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)
