    b=2+a from third equation. Plug that b into the b of the first equation. Now you have c's and a's in the first equation. Solve the system with the second equation for a and c. Plug a in to solve for b.

    that means you can't solve for the system then, so its just b=2+a and c=a+1... check to see if your equations are correct though, seems odd this would be a question on its on
