# How can you make this equation solvable

How can you make this equation right?

5+4+5=550

Note

• You can not change the equation, of course
• You only get to put ONE LINE through anywhere on the equation
• Similar questions have been asked before, but I think yours has a typo. 544+5 = 549, not 550. – Kingrames Sep 30 '16 at 20:56
• @Kingrames Or 5+5+5=550, giving 545+5=550. – IAmInPLS Sep 30 '16 at 21:24

$5+4+5\ne550$
$544+5=550$
Which is valid in base $9$:
$(5\times9^2+4\times9^1+4\times9^0)+(5\times9^0)=(5\times9^2+5\times9^1+0\times9^0)$
$(405+36+4)+(5)=(405+45+0)$
$445+5=450$
$450=450$
