There is no solution.

We have the equation #10y+9-2y=8y-3#

Add #3# on both sides.

#10y+9-2y+color(red)3=8y-3+color(red)3#

#10y-2y+12=8y#

#8y+12=8y#

Subtract #8y# from both sides.

#8y+12-color(red)(8y)=8y-color(red)(8y)#

#12=0#

As we know #12!=0#

Therefore there is no solution for this equation.

#"Undefined or Inconsistent Equation"#

#10y + 9 - 2y = 8y - 3#

Simplify..

#10y - 2y + 9 = 8y - 3#

#8y + 9 = 8y - 3#

Collect like terms..

#8y - 8y = - 3 - 9#

#0 = - 12#

Hence this is an #"Undefined or Inconsistent Equation"#
