Answer:
(x, , y) = ( 3 , 1 )
Step-by-step explanation:
y = -3x + 10
I. e 3x + y = 10. .........[eq. 1]
y = 4x - 11
I. e - 4x + y = -11 ......[eq. 2]
By subtracting eq. 2] from [eq. 1], we get,
3 x + y = 10
_
- 4x + y = -11

---------------------
7x. = 21
x = 21 / 7
x = 3
by substituting x = 3 in y = - 3x + 10
y = -3 (3) + 10
y = -9 +10
y = 1
