Question

solve for y in the first equation.

x – 3y = –6
2x – 7y = 10

Answer 1

its one of these answers ;
1/3x+2
- 1/3x+6
-x+2
-1/3x +2

Answer 2

please help:) i don't want the answer i just want help

Answer 3

write the given equation in the form of y=mx+c

Answer 4

first, take x onto the right hand side.

Answer 5

so i think that you need to calcule the x from second equation and this resulted value of x you need just substitute in place of x in the first equation and in this way will get the y from the first equation

Answer 6

let me try

Answer 7

hope so much that is understandably

Answer 8

so if you need to calcule the x from second equation what will be the first step ?

Answer 9

assum to both sides 7y

Answer 10

so than what will get ?

Answer 11

don't i need to get y by itself? wouldn't it be - 2 on both sides?

Answer 12

because your exercise is to solve for y from the first equation ,yes ?

Answer 13

yes

Answer 14

so than you need to get a value of x from the second equation and this value of x will need to substitute in place of x in the first equation

ok ?

Answer 15

ok

Answer 16

so than calcule please the first step how i have wrote it before little up

what will get ?

Answer 17

2x-7y=10 subtract 7y on both sides and get 2x=3 divide by 2 on each side and get 1.5

Answer 18

why ? how can you subtracting from 10 the 7y ?

Answer 19

oh my word i'm confused, i got - 1/3x+6 as the answer is that correct?

Answer 20

please write it here step by step

Answer 21

adding to both sides 7y will get

2x=10+7y

yes ?

Answer 22

so than from this how you will get the x ?

Answer 23

so do you like to continue it ?
