Solve using elimination 3x-4y=-14 and 3x+2y=-2
(2,2)
(-2,-2)
(-2,2)
(2,-2)

(-2,2)

Step-by-step explanation:

3x-4y=-14

2(3x+2y=-2)

3x-4y=-14

6x+4y=-4

9x=-18

x=-2

3(-2)-4y=-14

-6-4y=-14

-4y=-8

y=2

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay
