if all nos in the equation y/y+101 = 11in base 2, solve for y
I converted to base 10 and assumed you meant to have brackets in the following way
y/(y+5) = 3
crossmultiply...
y = 3y + 15
2y = -15
y = -15/2 in base 10
or
y = -1111/10 in base 2
y/(y+5) = 3
crossmultiply...
y = 3y + 15
2y = -15
y = -15/2 in base 10
or
y = -1111/10 in base 2
