PLZ HELP I'm fr super confused I'll give BRAINLIEST plz show the work

First answer is y = 7

Second answer is x = -1

Step-by-step explanation:

First answer explanation:

-x + 5y  = 5 and

x + 2y = 9

we can add those 2 together to eliminate the x value then continue to solve for y

7y = 14

divide both by 7

y = 7

Second answer explanation:

-3x + 2y = 13 and

5x - 4y = -25

This one we need to multiply the top equation to get the y's to eliminate once added together.

multiply the top equation by 2

-6x + 4y = 26

then add both equations together like the last one (This time the y is gone because the -4y and +4y cancel each other out)

-6x = 26

5x = -25

-1x = 1

divide both sides by -1

x = -1

a negative exponent is translated as follows:

so, we have
