Question

What is the justification for step 3 in the solution process?

0.8a − 0.1a = a − 2.5
Step 1: 0.7a = a − 2.5
Step 2: -0.3a = -2.5
Step 3: a = 8.3

Answer 1

is letter A .the division property of equality

Explanation:

Hope it help you!!

Answer 2

value of a=8.333

Explanation:

we take equation two and hence we divide both side by -0.3

hence

-2.5/-0.3

=8.333
