You don't need 3 equations to get a general solution. To do this use the equations x-3y-z=0 and -x+2y+0z= -3. Start out by letting z = t. Then solving those 2 equations simultaneously, your x's cancel out leaving you with -y-z=-3. But since z=t, then -y=-3+t or y=3-t. Now sub that in for y in the first equation, along with the fact that z=t to get x-3(3-t)-t = 0 and solve for x. x=9-2t. So a general solution for this would be (9-2t, 3-t, t)
Answer:
45, 47
Step-by-step explanation:
Their average, 92/2 = 46, is the even integer between them. The two integers of interest are 45 and 47.
___
Any consecutive integers of the same parity (odd or even) differ by 2. If x is the smaller, then x+2 is the larger.
We suppose you're supposed to write the equation ...
x + (x+2) = 92
2x = 90 . . . . . . subtract 2
x = 45 . . . . . . . .the smaller integer is 45; the larger one is x+2 = 47.

Answer: 51
Explanation: The range of a data set is the difference between the largest number in the data and the smallest number in the data set which in this case is 54 - 3 of 51. So the range of this data set is 51.
