Mathematics
1 answer:
BigorU [14]3 years ago
5 0

Answer:

x=7, y= 8

Step-by-step explanation:

x+y=15

x+2y=23

Subtract the first equation from the second equation to eliminate x

x+2y=23

-x-y=-15

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

  y = 8

Now we can find x

x+y = 15

x+8 = 15

Subtract 8 from each side

x+8-8=15-8

x = 7
