Solve the given system of equations.

2y = - x + 9

3x - 6y = - 15

The solution to the system is (,).

The given equations are:

1) 2y = - x + 9

⇒ x = 9-2y

2) 3x - 6y = - 15

⇒3x = 6y - 15

x = 2y - 5

Equating the values of x, we get:

9 - 2y = 2y - 5

9 + 5 = 4y

14 = 4y

y = 3.5

Using this value of y in equation 1 we get:

x = 9 - 2 (3.5) = 2

So, the solution set is (2, 3.5)
