~~~~~~~~~~~~~~~~~~~~~~

Nice problem !!   Thanks for posting it !   It has nice solution,  too.

Two eggs with bacon cost $2.70.

One egg with bacon costs $1.80.


HENCE (!), one egg costs exactly $2.70 - $1.80 = $0.90.   Agree ?


Now only one step remains to reveal that the bacon itself costs $1.80 - $0.90 = $0.90.


Answer. The bacon alone costs $0.90.

Solved (!)


It is how the Elimination method works
I explained it to you here without using equations.

I used the words only (!!).
