Question

X-y=12 x+y=3 what is x and y and i need to show work ty

Answer 1

Answer:

x=12 y=9

Step-by-step explanation:

first we need to do this equation to get X

we don't have y so y=0

x-(0)=12

we eliminate the 0

x=12

now, we have X, now we need to find Y

substitution

x+y=3

12+y=3

y=3-12

y= 9
