Hey there :)
We can solve 2 ways: With a calculator and Without
With:
√53 = 7.28
Therefore this lies between 7 and 8
Without:
6² and 7² = 36 and 49
Still, the values are less than 53, which means √53 does not lie between 6 and 7
7² and 8² = 49 and 64
53 is between both values, therefore √53 lies between 7 and 8
Your answer will be option B) 7 and 8
-3x+2y=-3
(y-4x=1)x2
-3x+2y-2y+8x=-5
5x=-5
x=-1
-3x+2y=-3
-3(-1)+2y=-3
2y=-6
y=-3
So you answers are X=-1, Y=-3
