Let the number be x: 4x+29 = 93 4x = 93-29 4x = 64 x = 16
8x + 23 + 4x - 7x = 64; Find X To make this easier, add like terms: (8x + 4x - 7x) + 26 = 64 Use the order of operations: (12x - 7x) + 26 = 64 5x + 26 = 64 -26 -26 5x = 38 5 5 Finally: x = 7(3/5)
12x - 9y = 6, 12x + 20y = 64 29y = 58 y = 2 x = 2
The answer is 64.
64 is the cube of 4 so: x3 + 64 = (x + 4)(x2 - 4x + 16)
