How do you get the answer for this??? 0.4y-12=-20?

Question

Does anyone know how to solve this math problem?

Answer 1

0.4y-12=-20

      +12  +12

0.4y = -8

0.4y/0.4 = -8/0.4

y = -20

Check your work

0.4(20) - 12 = -20

-8 - 12 = -20

Yep

y = -20

Answer 2

0.4y - 12 = -20----add 12 to both sides

0.4y = -8----divide both sides by 0.4

y = -20

Answer 3

0.4y -12= -20

Add 12 to both sides and your left with:

0.4y= -8

Now, divide each side by 0.4 to find y

You get: y = -20

hope this helps

Answer 4

Add 12 to both sides of the equality and then divide both sides by .4

Answer 5

0.4y-12=-20

=0.4y=-20+12

=0.4y=-8

=y=-8/0.4

=y=-20

........20

.....4/80

........8

There's a negative sign on eight so: y-20.

Check:

0.4y-12=-20

=0.4(-20)-12=-20

=-8-12=-20

=-20=-20

Answer 6

0.4y - 12 = -20

0.4y = -20 + 12

0.4y = -8

y = -8/0.4 = -80/4 = -20
