4(y-7)+2y=8?

Question

i got 6 but i don't think its right please explain thanksss

Answer 1

y= 6 it's right

4(y-7)+2y=8
4y-28+2y=8
6y=28+8
6y=36
y=6

you are right :)

Answer 2

I got 6 as well. Did you plug in 6 for y to test it?

4(6-7) + 2*6=8
4(-1) + 12 = 8
-4 + 12 = 8
8=8

Now here the work for my answer...

4(y-7)+2y=8
4y-28+2y=8
6y-28=8
6y=36

36/6 = 6 so y=6

Answer 3

You its 6

4(y-7)+2y=8 Distribute the 4
4y-28+2y=8 Simplify
6y-28=8 Add 28 to both sides
6y=36 Divide both sides by 6
y=6

Answer 4

u are correct! believe me i was in math honor roll 4yrs in high school 10 years ago..lol but yes u are right.
a) 4(y-7)+2y=8 (look down at b)

b)4y-28+2y=8 (remember PEMDAS; parenthesis, exponent, multiply, divide, add, subtract. multiply 4 times "y" and "-7" then write out the equation as is. u have to get rid of the parenthesis first!)

c)4y-28+2y=6y (remember to always combine the like terms, in this case add 4y+2y=6y-28=8)

d)6y-28=8 (u must try to cancel out the -28 by adding a positive to it so u can get 6y alone:
e.g. 6y-28=8
+28=28 (as u can see the -28 and +28 cancel out and now add 28 + 8 = 36. remember, what u do to one side of the equal sign, u must do to the other side.)

e) 6y=36 (the result is when u cancelled out "28" and added 28+8. since u want to find the answer for "y", u must cancel the "6" by dividing each side by 6)

f) y=6 (since 6 goes evenly into 36, your result is 6!) and u are very welcome

Answer 5

4(y - 7) + 2y = 8
4y - 28 + 2y = 8
6y = 36
y = 6

Looks like you were right!

Answer 6

4(y-7)+2y=8
4y-28+2y=8
6y=8+28
6y=36
y=36/6
y=6
your answer is absolutely allright.

Answer 7

4(y-7)+2y=8
4y-28+2y=8
6y-28=8
6y=36
y=6

Answer 8

4y-28+2y=8
6y-28=8
6y=36
y=6

Answer 9

why u think u r wrong u r always right..........

4(y-7)+2y=8
4y-28+2y=8
6y=28+8
6y=36
y=6
so ur answer is right....dont worry dear
