Answer:
3x-2y=3......Eq1
2x-1y=10.....Eq2
Step-by-step explanation:
dx = | 3 -2 |
| 10 -1|
°Cross multiply
= [ 3*(-1) - 10*(-2) ]
= -3 - (-20)
= -3 + 20
= 17
dy = | 3 3 |
| 2 10|
°Cross Multiply
= ( 3*10 ) - ( 2*3 )
= 30-6
= 24
d = | 3 -2 |
| 2 -1 |
° Cross Multiply
= [ 3*(-1) ] - [ 2*(-2) ]
= -3 - (-4)
= -3 + 4
= 1
x = dx^d = 17^1 = 17
y = dy^d = 24^1 = 24
(x,y) = (17,24)
