HELP PLZ!!!

Answer 1

Answer:

Multiply 2x+3y =-1 by 5. Multiply 3x-5y =-1 by 3. Add the resilting equations together.

Step-by-step explanation:

As we need to eliminate the y term we could find the the common multiple of the y terms coefficients. As we can see the coefficients are 3 in the left member and -5 in the center member that means 15 will be the common multiple.  

Then we multiply for the proper number to get the common multiple:

(2x+3y =-1)*5  ---> 10x +15y = - 5

(3x- 5y = 10)*3 ---> 30x - 15y = 10

Then by add term by term:

10x +15y = - 5

30x - 15y = 10

------------------

40x + 0y = 5

Which solution will be x = 1/8

Answer 2

Multiply 2x+3y=-1 by 5 and 3x-5y=10 by 3

3y*5=15y and -5y*3=-15y

Add -15y and 15y you have no y values left.

Your main focus is going to be on the y values. What can you multiply each y value by to get the same number so that when you add the positive and negative you get 0.
