We can divide 286 into w,x,y and z.
We know that w+1=x-2=3y=z/4
So, we make all of them into terms of x.
and we know that w+x+y+z=286.
but x-2 is not divisible by 3, so, make 3 a common denominator and multiply 286 by 3
so, 3x-9/3 + 3x + x-2/3 + 12-24/3 = 858.
And that equals to 19x-35=858
so, y=47-2/3= 15
check:- 47+44+15+180= 286
