Answer:

-4

Step-by-step explanation:

a - 15 = 4a - 3

Subtract "a" on both sides

a - a - 15 = 4a - a - 3

-15 = 3a - 3

Add 3 on both sides

-15 + 3 = 3a - 3 + 2

-12 = 3a

Now divide by 3 on both sides to isolate the variable

-12/3 = 3a/3

-4 = a

Check

Now that we have what "a" is we can substitute that and see if its true

a - 15 = 4a - 3

-4 - 15 = 4(-4) - 3

-19 = -16 - 3

-19 = -19 CORRECT

Hope this helped!
