I believe the answer is 0,0 but don't qoute me because one zero in your set is the same answer as no zeros in your set but two zeros is undefined.
X = y + 3
2x + y = 9
Solution..
---------------
Substitute for x=y+3 in the second equation...
2x+y = 9
2(y+3)+y=9
2y+6+y=9
3y+6=9
3y=9-6
3y=3
y=3/3
y=1....
Substitute for y=1 in the first equation...
x=y+3
x = 1+3
x=4..
Am sure the answer is quite evident now...
1a+18=7a
18=7a-1a
18=6a
6a=18
a=18/6
a=3
Answer: 107.5
Steps:
