Question

who can help explain how to solve this problem for me... 5(31/16)+3y=-11

Answer 1

ok first think you are going to want to do is clear the fraction because, well lets face it nobody likes them.

Answer 2

how do i do that?

Answer 3

to do this you are going to multiply everything by 16 so that you end up with \[31+48y=-176\] no we have a much easier number to work with

Answer 4

the next step is to get your varibles on one side and constants on the other

Answer 5

ok

Answer 6

retype in the equation please

Answer 7

48y=-176-31?

Answer 8

was the first number 5 and 31/16 ?

Answer 9

5 times 31/15

Answer 10

ok thats going to change up the numbers a bit

Answer 11

oh ok

Answer 12

if you can please explain to me i have finals next week and a exam friday i want to really understand this!

Answer 13

but then you after you have transposed your constants and vvaribles you divide both sides by the coeficent of the varible to get your answer

Answer 14

im really confused now?

Answer 15

hello?

Answer 16

x=-331/48 try to simplify

Answer 17

how did you get that?

Answer 18

5(31/16)+3y=-11 => 155+48y=-176 =>48y=-176-155 => 48y=-331
=> y=-331/48

Answer 19

ok let me see if i get it right

Answer 20

it didnt come out right i think i did it wrong

Answer 21

it said to solve using the elimination method and it gave me 2 diffrent problems

Answer 22

5x+3y=-11
7x-2y=19

solve using elimination method

Answer 23

can u help me with this?

Answer 24

multiply the top function by 2 and the bottom function by 3 and tell me what you get

Answer 25

10x+6y=-22
21x-6y=38

Answer 26

then i would get 31x=16

Answer 27

ok now you are going to combine the top and bottom function, and yes

Answer 28

so then i would get x= 31/16

Answer 29

after that i dont know what to do

Answer 30

it would be 16/31

Answer 31

sub that in for your x value inorder to get your y value

Answer 32

so i would do 5(31/16)+3y=-11

Answer 33

5 times 31/16

Answer 34

yea

Answer 35
