Answer:

(3, 2)

Explanation:

The system of equations can be solved using elimination to eliminate one variable and solve for the other. Given the two equations:

3x + 4y = 17 and -4x - 3y = -18, we need to have opposite coefficients to eliminate a variable. Multiplying the first equation by '3' and the second by '4':

3(3x + 4y = 17) = 9x + 12y = 51

4(-4x - 3y = -18) = -16x - 12y = -72

-7x = -21

x = 3

Solve for y: 3(3) + 4y = 17 or 9 + 4y = 17

y = 2
