4. Solve using elimination.
4x -3y = 9
3x +2y = 11

x=3, y=1

Step-by-step explanation:

2(4x-3y=9) Multiply these two equations to cancel out the y using elimination

3(3x+2y=11)

8x-6y=18 Add these two equations to cancel out the y using elimination

9x+6y=33

17x=51 Solve for x

x=3

4(3)-3y=9 Plug in x=3 into the original equation

3y=3 Solve for y

y=1

lockers 1, 4, 9, 16, 25, 40, and 49 are open
