I DONT WANT TO FAIL!!!! PLEASE HELP ME WITH THE CORRECT ANSWER, WILL MARK AS BRAINLIEST!!!

Answer 1

Answer:

x = -24

y = 66

Step-by-step explanation:

12x+9y = 102

12x+16y = 432

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

y = 66

4x + (66*3) = 102

198-102 = -96

-96 / 4 = -24

Answer 2

Answer:

solution is $(6,10)$

Step-by-step explanation:

$4x+3y=54$

$3x+9y=108$

WE use elimination method to solve for x and y

Multiply the first equation by $-3$

$-12x-9y=-162$

$3x+9y=108$

Now add both the equations, we will get

$-9x=-54$

Divide by   $-9$ on both sides

$x=6$

Now we plug in the x value in first equaiton and find out y

$4x+3y=54$

$4(6)+3y=54$

$24+3y=54$, subtract 24 on both sides

$3y=30$

Divide both sides by 3

$y=10$

So solution is $(6,10)$
