Answer 1

I'll teach you how to solve x= 12 - y, 2x + 3y = 29

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

x= 12 - y, 2x + 3y = 29

Substitute x=12-y:

[2(12-y)+3y=29]

Isolate y for 2(12-y)+3y=29:

2(12-y)+3y=29= y= 5

Substitute y=5:

x=12-5

12-5= 7

x=7

Your Answer Is (C) x=7, y=5

plz mark me as brainliest if this helped :)

Answer 2

Answer: c

Step-by-step explanation:

2x+3y=29

2(12-y)+3y=29

24-2y+3y=29

-2y+3y=5

Y=5

X=12-y

X=12-5

X=7
