Answer:

x = 5 and y= 15

Step-by-step explanation:

3x + 2y = 45

4x - y = 5 (multiple both sides by 2)

3x + 2y = 45

8x - 2y = 10

--------------------( add side with side)

11x + 0 = 55

or x= 55/11 = 5

replace x =5 into 4x - y = 5 we have 4*5 - y = 5

20 - y = 5 or y = 20- 5= 15

So x = 5 and y= 15
