Math Homework...HELP!!!?

Question

Problem:
2/5(2y+1)=y-3
i can't figure it out. please help me.....

Answer 1

Distribute the 2/5 to the parenthesis:
4/5y+2/5=y-3

Then get the variables on the same side:
4/5y+2/5=y-3
-4/5 -4/5

2/5=1/5y-3

Then get the variable alone:
2/5=1/5y-3
+3 +3

3 2/5=1/5y

Finally, divide by 1/5:
3 2/5=1/5y
/ 1/5 / 1/5

17=y

17 is the answer.

Answer 2

First, multiply 2/5 times everything in the parenthesis.
4/5y + 2/5 = y-3
Get the unknowns (y) on one side
4/5 y - y + 2/5 = -3
Now move all the known numbers to the other side
4/5y - y = -3 - 2/5
Combine
-1/5y = -3 2/5 or - 17/5
To get rid of the fraction, multiply both sides by 5
y= 17

Check your work by replacing "Y" with 17

2/5(2.17)+1) = 17-3
2/5 . 34+1 or 2/5 . 35 = 14
17-3 = 14

Answer 3

y=17/3 or 5 2/3

Answer 4

multiply the whole thing by 5
so 2(2y+1)=5(y-3)
the distribute
4y+2=5y-15
then even out both sides
17=y
ther you have it
i hope this helps
:)
and good luck with the rest of your math

Answer 5

2/5(2y + 1) = y-3 : Do 2/5 to 2y and 1
.8y + .4 = y-3 : - .4 to both sides.
.8y = y - 3.4 now minus y or 1y to both sides
-.2y = -3.4 Now divide -.2 to both sides
y = 17

Answer 6

step 1: distribute the 2/5 to the (2y +1)
so you get 0.8y +2/5=y-3

then you add three to both sides so you get
0.8y+ 3 2/5 = y


hope that helps!

Answer 7

2/5(2y) + 2/5(1)=y-3
(4y)/5+ 2/5=y-3 multiply the whole thing by 5 to make it easier to work with
4y+2=5y-15
17=y

plug it in to check:
2/5(35)=14
14=14, so it works

Answer 8

y = 17
first time both side by 5,
2(2y+1) =5y-15
Then mulitple the 2 out
4y+2 =5y-15
move it around you got y=17

Answer 9

2/5=whatever(2+1=3 divide by 2)
multiply the quoteint of 2/5 by the answer of the question in parentases. and youl get most of the answer..... but thats all i can help with........... sorry

Answer 10

i have been doing the same kind of problems lately, so i'm guessing ur in 8th grade. y=153/25 u might need to simlify, but sometimes you wont get marked down for not simplifing
