Answer:

Ashley should have added 4.5 to both sides.

Step-by-step explanation:

Given expression:

$-4.5+m=17$

Ashley's solution:

Subtracted 4.5 to both sides and got,

$m=12.5$

Correct solution:

Adding 4.5 to both sides.

$-4.5+m=17$

$+4.5$ $+4.5$

∴ $m=21.5$

Error made by Ashley was subtracting 4.5 both sides. Instead he should have added 4.5 both sides.
