Answer:
x = 5 and y= 15
Step-by-step explanation:
3x + 2y = 45
4x - y = 5 (multiple both sides by 2)
or
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

3x-3-4x+2=8x-8
3x-3-4x+2-8x+8=0
-9x+7=0
-9x=-7
x= 7/9
