Answer 2

Since Y is equal to Y you can write it like this:
2x + 19 = x + 7 Now use algebra and solve for x.
Then substitute your x value to either equation and solve for Y.

Answer 3

From 2nd equation
Y= x+7
We get
x =y -7 -------substitute this value in equation 1...
Now
Y= 2(Y-7)+19
Y= 2Y-14+19
Y- 2Y= 5
Y= -5
AND THEREFORE ;
X= -12.....
