Solve the system of equations.%0D%0A7x+3y=−25%0D%0A−7x+9y=−47(1 point)%0D%0A(, )

Answer 1

To solve the system of equations:

7x + 3y = -25
-7x + 9y = -47

We can add the two equations together to eliminate the x term:

7x + 3y - 7x + 9y = -25 - 47
12y = -72
y = -6

Now, we can substitute y = -6 back into one of the original equations to solve for x:

7x + 3(-6) = -25
7x - 18 = -25
7x = -7
x = -1

Therefore, the solution to the system of equations is x = -1 and y = -6.
