"3x + 5y = 2z" doesn't ask any question.
If you're looking for numbers for 'x', 'y', and 'z' that make the statement true, there are
an infinite number of sets that do it.
A few of them are:
x=1, y=3, z=9
x=2, y=4, z=13
x=3, y=5, z=17
If you want to set up a puzzle where there's only one correct answer ... only one secret set of
values for 'x', 'y', and 'z' that solves the puzzle, then you need two more equations.
The one equation you gave us is the equation of a line in 3 dimensions. Every point on the line
has the coordinates (x, y, z), and every point satisfies the equation.
The intercept of -3x + 5y - 2z = 60 are (-20, 0, 0), (0, 12, 0) and (0, 0, -30).

3x+5y=48 5y=48-3x-3x+5y=12 -3x+(48-3x)=12-6x=-36x=65y=48-3(6)5y=30y=6(6,6)
x=(-5y-1)/3

No.
X = -2(13 + y) / 3x = 5y / 4 - 1
