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:
Please give me brainliest
L has "x -3"
S has "x"
x + x - 3 = 17
2x -3 (+3) = 17 (+3)
2x = 20
2x/2 = 20/2
x = 10
Leona has x - 3, or 10 - 3, or 7 dollars
Skye has 10 dollars
hope this helps
