Ask for an equation, x + y + Z = 1, x-z = y, YX = 1, x.y.z is equal to?

Ask for an equation, x + y + Z = 1, x-z = y, YX = 1, x.y.z is equal to?

Three equations, three unknowns should be solved,
After finishing, we can get x + y + Z = 1, 1 X-Y-Z = 0, 2 x * y = 1, 3
① We can get: x = 1 / 2 by substituting this result into: y = 2
Finally, we can get z = - 3 / 2 by substituting x = 1 / 2; y = 2 into 1;
The results are: x = 1 / 2; y = 2; Z = - 3 / 2

It is known that the root of the equation (1 / 3) ^ x = 2A + 1 / 7-a about X is a positive number

x>0
0

The least common multiple of three continuous natural numbers is 60, and the sum of these three numbers is ()
There should be a formula to solve the problem

60 decomposition quality factor: 60 = 2 × 2 × 3 × 5
(1) The quality factor is 4 × 3 × 5
Get the first group of three continuous natural numbers: 3, 4, 5, and 12
(2) Using short division, 2|__ a___ b____ c___
2 3 5
It can be seen that a = 4, B = 6, C does not change to 5
Get the second group of three continuous natural numbers: 4, 5, 6, and 15

The sum of three consecutive even numbers is 60______ 、______ 、______ ．

Let the smallest one of the three continuous even numbers with sum 60 be x, and we can get the equation: x + X + 2 + X + 4 = 60 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 3x + 6 = 60 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 3x = 54 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 18, then x + 2 = 18 + 2 = 20, x + 4 = 18 + 4 = 22
