write random numbers and find the result later
make sure you don't write 2 euations that are the same like x+y+z=1 and 2x+2y+2z=2


3x+2y-4z=?
5x-6y+3z=?
x+3y-5z=?

if we evaluate for x=3, y=5 and z=2

3x+2y-4z=11
5x-6y+3z=-9
x+3y-5z=8

there, a system of 3 euations with solution of (3,5,2)

pshichka [43]

Answer:

x = 13/3

Step-by-step explanation:

4(8x-3) - 30x = 5(x-5)

Distribute

32x - 12 - 30x  = 5x -25

Combine like terms

2x -12 = 5x-25

Subtract 2x from each side

2x-12-2x = 5x-2x -25

-12 = 3x-25

Add 25 to each side

-12+25 = 3x-25+25

13 = 3x

Divide each side by 3

13/3 = x

Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the differenc
Mademuasel [1]
Let X is the random number Erik thinks of, and Y is the random number Nita thinks of.
Both X and Y are in the range from 0 to 20.
<span>X<=20
Y<=20
If the difference between their two numbers is less than 10, then Erik wins.
The difference between the two numbers can be written X-Y, or Y-X depending on which number (X or Y) is greater. But we do not know that. In order not to get negative value, we calculate absolute value of X-Y,  written |X-Y| which will give positive value whether X is greater than Y or not.
If |X-Y|<10 Erik wins.
