ok what else did you want to know

anonymous · Answer

how to find y

dumbcow · Answer

a lot of steps were done for you in other post

dumbcow · Answer

Remember the goal when using elimination is to multiply equations by numbers or scale factors which will allow a variable to cancel out if the equations are added together

anonymous · Answer

we got y in 4 steps: 
1)multiply the first equation by 3 get 
$$-6x+5y=-15$$ 
2) multiply the second equation by 2 you get
$$6x-7y=9$$
3) add
$$-2y=-6$$ 4) divide by -2
$$y=3$$

anonymous · Answer

now you need x. replace y by 3 in either equation, get x

anonymous · Answer

he/she reposted it

anonymous · Answer

replace y by 3
$$6x-7(3)=9$$
multiply
$$6x-21=9$$
add 21
$$6x=30$$
divide by 6
$$x=5$$
