see
3x+45x+6x=25
den, 54x=25
or, x=25/54
since y=54x
so y=25

Simplifying
3x + 45x + 6x = 25
Combine like terms: 3x + 45x = 48x
48x + 6x = 25
Combine like terms: 48x + 6x = 54x
54x = 25
Solving
54x = 25
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '54'.
x = 0.462962963
Simplifying
x = 0.462962963

if you look at the "equation".. annswer is right there... y=25
it really doesn't matter what x is at this point.. yur not trying to solve for x.. the equation wants y, and since it already says that the whole thing = 25, then y=25
If you want to solve for 2 unknowns you need 2 equations

simplified
y = 54x = 25
y = 25
x = 25 / 54 = 0.462963
