Question

So if I have the problem 1/4y+5=1/7y do I multiply everything by 7?

Answer 1

you could however that wouldn't get you nice coefficients

Answer 2

go ahead though

Answer 3

actually do it because it will make the substraction easier

Answer 4

I don't get how to do these ! I keep getting them wrong :,(

Answer 5

so you'll get 7/4y +35 = y

Answer 6

did you get that right?

Answer 7

yes

Answer 8

now you need to get your y terms on one side

Answer 9

then I subtract y from both sides?

Answer 10

you can either minus the 1y and minus the 35 or you can just minus 7/4y

Answer 11

basically you want to load one side with y and the other just be a constant or a number

Answer 12

i would minus 7/4 y because then you wont have to do two steps

Answer 13

so you should get
35=1y-7/4y

Answer 14

Multiply both sides by y then you get the simpler: 1/4 + 5y = 1/7 to get
5y = 1/7 - 1/4 = (4-7)/28 = -3/28
Ans. y = -3/(5*28)

Answer 15

-3/4y= 35

Answer 16

35*-4/3 = y

Answer 17

So the answers 35-4/3=y ?

Answer 18

*

Answer 19

are the y's in the denominator or in the numerator

Answer 20

there not in either there to the side of the fractions

Answer 21

so its 1/4 y +5= 1/7 y

Answer 22

so it is \[\frac{1}{4}y+5=\frac{1}{7}y\]

Answer 23

Yes my love !

Answer 24

personally i like using whole numbers instead of fractions so i would use the least common multiple of 4 and 7 which is 28 so i'd multiply everything by 28 and get:

7y + 140 = 4 y and then subtract 4y from both sides:
7y-4y + 140 = 4y - 4y
3y + 140 = 0
then subtract 140 from both sides
3y+140-140=-140
3y=-140
divide both sides by 3
3y/3=-140/3
y=-140/3

Answer 25

your answer will be -140/3

Answer 26

which is simply
