For number 7, x is smaller than 9, for number 8, x is bigger than 8.
idk i think u would have to do some really good math for that.
Answer:
y= 28/17
x= 57/17
Step-by-step explanation:
5x + 2y = 22
-2x + 6y = 3
(2)(5x + 2y = 22)→ 10x + 4y = 44
(5)(-2x + 6y = 3)→ -10x +30y = 15
Add this last eq → 34y=56 → y= 28/17
Replace this in any equation
-2x + 6(28/17) = 3 → x= - (54/17-168/17)/2 = 57/17
It makes it easier because you are finding these smallest possible factors that go into 20
