X-2y=4. -3x+5y=-3. solving linear systems using multiplication and addition show your work

Answers

-3x+5y=-3
3x -6y= 12
Multiplied the first equation by 3 so the x's will cancel.
Adding the two equations we get
-y=9
y=-9
Now plug y back in to either equation and solve for x. x-2(-9)=4
x+18=4
x=-14
(-14,-9)

Whch faction is smaller 5/6 or 5/8

Answers

5/8 is the smaller fraction
5/6 is 1/6 away from 1
while 5/8 is 3/8 away from 1
Next, 3/8>2/8 
(2/8=1/4)

So, 5/8 is more than 1/4 away from 1
Because 1/4>1/6
--> 5/8 is farther away from 1 than 1/6
Thus, 5/8 is smaller.

A shortcut I've been taught is attached

Explanation of attached file: 
40 is above 5/6 
while 30 is above 5/8
since 40>30 --> 5/6>5/8

Hope this helps!
