Answer:
(-2, 1)
Step-by-step explanation:
Systems of equations can be solved using different methods.  For this set of systems, you can multiply each equation by a factor in order to eliminate a variable and solve for the other variable: 
-3(-5x - 3y = 7)  or 15x + 9y = -21 
5(-3x - 4y = 2)  or <u>-15x -20y = 10</u>
                                     -11y = -11 
                                         y = 1
Solve for x:  -5x - 3 = 7
Add 3 to both sides:  -5x -3 + 3 = 7 + 3 or -5x = 10 
Solve for x: x = -2 
(-2, 1)
