Answer:

x =50 and y= 15

Step-by-step explanation:

3x + 10y = 300

2x + 3y = 145

By elimination method

2 (3x + 10y) = 2*300

3 (2x + 3y) = 3*145

= 6x + 20y = 600

6x + 9y = 435

By subtracting we get

6x + 20y = 600

- 6x + 9y = 145

= 11y = 165

= y = 165/11

= y= 15

By putting the value of y in 2nd equation we get

2x + 3*15 = 145

2x + 45 =145

2x = 145-45

2x = 100

x = 50

Hope it's correct.
