What is the solution of the system?

Step-by-step explanation:

Try substitution, using the fact that x - y = 17 is equivalent to x = 17 + y:

4y + 9(17 + y) = 82, which simplifies to 13y + 153 = 82.

Subtracting 153 from both sides, we get:  13y = -71, so y = -71/13, or y = -71/13

Substituting -71/13 for y in the second equation yields

x - (-71/13) = 17, or x + 71/13 = 17.

Finally, we subtract 71/13 from both sides, obtaining the value of x:

x = 17 - 71/13, or 150/13

The solution of this system is (150/13, -71/13).

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
