Solve the system, or show that it has no solution. (If there is no solution, enter NO SOLUTION. If there are an infinite number of solutions, enter the general solution in terms of x, where x is any real number.)

- x + y = 3

3x - 4y = - 16

Now

- 3x + 3y = 9

3x - 4y = - 16

Adding them

- y = - 7

y = 7

For x

- x + 7 = 3

- x = 3 - 7

- x = - 4

x = 4

Hence {x,y} = {4,7}
