Question

7x - 3y = 4 2x - 4y = 1 The solution to the system of equations is _____. (13/34, -15/34) (3/22, -7/22) (13/22, 1/22)

Answer 1

are you asking for someone to check or are those the options?

Answer 2

those are options

Answer 3

it is (13/22, 1/22)

Answer 4

3x - 4y = 7

3x + 2y = -5

When the second equation is subtracted from the first, the resulting equation is _____.

-6y= -12
-6y= 12
-2y= -12
2y= 12

Answer 5

the equations you put are
7x-3y=4 and
2x-4y=1
so if you multiply the first one by 4 and the second one by 3(to get the ys equal) you get
28x-12y=16 and
6x-12y=3
so you would subtract the second one from the first one and get
22x=13
then divide by 22 and get
x=13/22.

Answer 6

i understand that i need help with other one

Answer 7

oh! okay, well you would set it up the same way then..

Answer 8

3x-4y=7
3x+2y=-5
you would subtract the second from the first to get rid of x.
