since there is already 2 7x's we can multiply a positive 1 so we can eliminate the 7x's

+1 (-7x-4y=-7) = 7x+4y=7

7x+4y=7

-7x-2y=-4

2y=3

divide 2 on both sides to isolate y

y=2/3

now to find x you will have to plug in 2/3 to one of the original equations

-7x-2(2/3)=-4

-7x-1.33=-4

add 1.33 to both sides

-7x=2.67

divide -7 on both sides

x=0.38

hope this helped hon:)

Plz help I need the answer plz
BaLLatris [955]

If the equation is

\frac 5 2 s = \frac 3 2 s + s

that's true for all s, since 3/2+1=5/2

So all of them result in true statements

Answer: All of the above

Let's just do one for yuks, s=5.

(5/2) s = 25/2

(3/2)s + s = 15/2 + 5 = 15/2 + 10/2 = 25/2  

That checks.
