x^2+ 30x + 81 = 0
x^2+ 27x + 3x + 81 = 0
x = -3, -27
y^2-9y -162 = 0
y^2-18y + 9y -162 = 0
y = -9, 18
Hence, no relationship can be established between x and y
This can be easily simplified by Approximation process
Given 39.96% of 649.85 13.07 = 45.14 - ? can be written as
40% of 650 13 = 45 - ?
Given equation can be written as
