OR x + y = 201 y = 201 - x z − x = 200 z = 200 + x x + y + z = x + 201 - x + 200 + x x + y + z = 401 + x x + y = 201 mean : x < 201 / 2 x < 100.5 ________________________________________ For example : If x = 101 y = 201 - x = 201 - 101 = 100 That not satisfie condi...

x + y = 201 y = 201 - x y > x that's why x < 201 / 2 x < 100.5 Nearest integer: x = 100 x + y = 201 y = 201 - x y = 201 - 100 y = 101 z − x = 200 z = 200 + x z = 200 + 100 z = 300 x + y + z = 100 + 101 + 300 = 501

17 m - 3 / 2 = 5 m + 14 Subtract 5 m to both sides 17 m - 3 / 2 - 5 m = 5 m + 14 - 5 m 12 m - 3 / 2 = 14 Add 3 / 2 to both sides 12 m - 3 / 2 + 3 / 2 = 14 + 3 / 2 12 m = 14 + 3 / 2 12 m = 28 / 2 + 3 / 2 12 m = 31 / 2 Divide both sides by 12 m = ( 31 / 2 ) / 12 m = 31 / ( 2 * 1...

a = first number b = a + 1 = socond number a b = 156 a ( a + 1 ) = 156 a ^ 2 + a = 156 Add 1 / 4 to both sides a ^ 2 + a + 1 / 4 = 156 + 1 / 4 a ^ 2 + a + 1 / 4 = 624 / 4 + 1 / 4 a ^ 2 + a + 1 / 4 = 625 / 4 ________________________________________ Remark : ( x + y ) ^ 2 = x ^ ...
