X + 3y = 9
3x - 3y = -13
--------------add
4x = - 4
x = -4/4
x = -1
x + 3y = 9
-1 + 3y = 9
3y = 9 + 1
3y = 10
y = 10/3
solution (-1,10/3)
Step-by-step explanation:
2x-y=7
x=(y+7)/2
again
x=(y-3)/2
now
solve it
310 is the correct answer . If you would like a explination why just let me know (:
P.s. could i please have brainliest
Answer:
