87-63 = 24
24 + 63 = 87
63 21,3 7,3,3 3 x 3 x 7 = 63
Multiply 90 x .63= 56.7 is 63% of 90
x2-2x = 63 x2-2x -63 = 0 => x = -7 or x = 9 So x must = 9 Check: 92-18 = 63
87-63 = 24
24 + 63 = 87
63 21,3 7,3,3 3 x 3 x 7 = 63
Multiply 90 x .63= 56.7 is 63% of 90
x2-2x = 63 x2-2x -63 = 0 => x = -7 or x = 9 So x must = 9 Check: 92-18 = 63
