6x+11y=180

no. this is not possible. there are two unknowns in this equation (x and y), but you only provide one equation which is not enough.
you can solve for x or y, but the solution would be in terms of the other variable.
for example:
6x+11y=180
solved for x in terms of y:
x = (-11y - 180) / 6
solved for y in terms of x:
y = -6(x - 30) / 11
you could graph this equation [and by 'this' equation, note that i'm not referring to a specific one because they are all actually the same equation changed around] if you wanted.

Pick any value for x you want. This particular equation describes the relationship which must exist between that value of x which you have chosen and its corresponding y value. For any x value you pick, y = (180 - 6x) / 11. So, if you've chosen x to be 1, then y = [180 - 6 (1)] / 11 = 174 / 11.
To answer your question then, x and y can be any complex number (i.e. any number of the form: a + bi, where a and b are any real numbers and i is the square root of -1).

hi
if x=1 then
6*1+11y=180
y=180-6/11
y= 15.81
if y=1
6x+11*1=180
x=180-11/6
x= 28.16666

6x + 11y = 180
6x + 11y - 6x = - 6x + 180
11y = - 6x + 180
11y/11 = - 6x/11 + 180/11
y = - 6x/11 + 180/11
The answer is y = - 6x/11 + 180/11
- - - - - - - - - - - - - - -
6x + 11y = 180
6x + 11y - 11y = - 11y + 180
6x = - 11y + 180
6x/6 = - 11y/6 + 180/6
x = - 11y/6 + 30
The answer is x = - 11y/6 + 30

You get to have another equation to find the values. Else it will be in terms of x and y.
x= (180-11y)/6
y=(180+6x)/11

u can substitute a var x or y with alpha.
if x is that then x= alpha,with alpha real
y=(180-6*ahpha)/11
u can give any value to the alpha now, and get var y with above formula

Presumably you're looking for integer values.
Is x=30, y=0 good enough?

if u have 2 unknowns, u need at least 2 equations to solve the unknowns

substitute a value for x and you will get the value of y which satisfies yhe equation..like this you can find infinite no. of values....

whether this question is incomplete or can have infinite values. put any value of x and u'll get corresponding value of y.
in this way u can have infinite values
