For the first one multiply each term by the LCM of 4 and 6, which is 12:-
15x -36 = 2y..................(1)
and second multiply by 5:-
2x + y = 9..............(2)
solving:-
from equation (2) y = 9-2x, substitute in equation (1):-
15x - 36 = 2(9-2x) = 18 - 4x
19x = 54
x = 54/19 = 2.84
so y = 9 - 2(2.84) = 3.32
Answer:

Step-by-step explanation:

Subtract 5/8 from both sides:-


Add like terms:-

Rule:- 
Subtract, 
Cancel common factor: 2
---------------

Now, subtract 3x from both sides:-


Divide both sides by -1:-
