I think it'd be better if you gave us some sort of diagram with it?
Answer:
y has the greatest value.
Step-by-step explanation:
1.23w = t
Divide both sides by 1.23.

--- (1)
1.01x = t
Divide both sides by 1.01.

--- (2)
0.99y = t
Divide both sides by 0.99.

--- (3)
From (1), (2) and (3), it is clear that y has the greatest value.
I would subtract the 2nd from the first one
so -4x - -2x = -2x
4y - 4y = 0
-20 - -2 = -18
-2x = -18
now I would divide that by -2 to get the value for x
so no we have x = 9
now you just have to substitute that into one of the equations and simplify to get y
-2 X 9 + 4y = -2
-18 + 4y = -2
4y =16
y = 4
Can u go closer I can’t see
