10x + 5y = 25
4x - 5y = 3
What’s is the solution ??

x=2, y=1

Step-by-step explanation:

10x + 5y = 25

4x - 5y = 3

Add the two equations together to eliminate y

10x + 5y = 25

4x - 5y = 3

14x    = 28

Divide by 14

14x/14 = 28/14

x = 2

Now find y

10x+5y = 25

10(2) +5y = 25

20+5y= 25

Subtract 20 from each side

5y = 25-20

5y = 5

Divide by 5

5y/5 = 5/5

y =1

the value of x is 2 and y is 1

Step-by-step explanation:

10x + 5y =25

4x -5y =3

14x = 28

x = 28/14

x =2

substitute the value of x in 10x + 5y =25,then we get

10*2+5y= 25

20 + 5y = 25

5y = 25-20

y = 5/5

y = 1

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

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
