–
3
2a=16
Add 19 to both sides
Subtract 19 from both sides
Multiply both sides by 19
Divide both sides by 19
Apply the distributive property
a=
Divide both sides by 2

Answer 1

Start with 2a − 19 = −3.

Add 19 to both sides (because −19 is being subtracted):
2a − 19 + 19 = −3 + 19 → 2a = 16.

Now divide both sides by 2:
a = 16/2 = 8.

So the correct steps are "Add 19 to both sides" and then "Divide both sides by 2", and a = 8.
