9a=
Add 10 to both sides
Subtract 10 from both sides
Multiply both sides by 10
Divide both sides by 10
Apply the distributive property
a=

Answer 1

It looks like the equation is: -9a − 10 = −19.

Step 1 — add 10 to both sides:
-9a − 10 + 10 = −19 + 10 → −9a = −9

Step 2 — divide both sides by −9:
a = (−9)/(−9) = 1

So a = 1.

(Notes: subtracting 10, multiplying/dividing by 10, or using the distributive property are not the needed steps here.)
