Question

Need help in Equation.... Solve: 6y + 15 = -6 + 3y
y=?

Answer 1

okay we need to bring all the y terms on one side and all the constants on the other.

Answer 2

can you do that step?

Answer 3

no

Answer 4

sorry

Answer 5

that's fine. let's do this one step at a time.

Answer 6

ok

Answer 7

we have 6y + 15 = -6 + 3y

lets subtract 3y on both sides

6y-3y +15=-6+3y-3y

what will this simplify to?

Answer 8

i dont really know this, im bad in eqations.

Answer 9

okay 6y-3y are like terms as the both have y so because of this we just subtract the numbers to get the answer.

6y-3y=3y

what about 3y-3y, what do you think it will equal?

Answer 10

0 ?

Answer 11

0y

Answer 12

because 0*anything=0 we can just write 0

perfect, so in our equation we now have
3y+15=-6+0
3y+15=-6

now we want to get the 15 to the other side, so i'm going to subtract both sides by 15

3y+15-15=-6-15
what will I get?

Answer 13

-7 ?

Answer 14

close, remember there is a negative in front of the 6
so -6-15=-21

Answer 15

ohh i subtract it , i get it

Answer 16

ok thank u

Answer 17

3y=-21

to get rid of the 3 we need to divide both sides by 3 and then we will have an answer for y

\[\frac{3y}{3}=\frac{-21}{3}\]

what is y equal to?

Answer 18

7

Answer 19

is it negative 7 ? or just positive ?

Answer 20

don't forget about the negatives so it will be -7

Answer 21

ok

Answer 22

you can always check by putting your value for y into the original problem
