Eliminate 2nd equation from 1st equation here:

3y = -27

y = -27/3

y = -9

Now, substitute the value in 2nd equation, x - (-9) = 13

x + 9 = 13

x = 13 - 9 = 4

In short, Your Answer would be: (4, -9)

Hope this helps!

What is the value of the 1 in 178
Igoryamba
The value of 1 in 178 is 100 since it is in the hundreds place.  The value of 7 in 178 is 70 and the value of 8 in 178 is 8.  The hundreds place carries numbers from 1 to 9.  Once you get to 10, you add a digit to the number such that you now have four total numbers and the first digit is in the thousands place.

n^r

n is the number of options, n=10, and r the number of times you have to place a digit, r=4.

10^4=10000
