Answer:
3/8
Step-by-step explanation:
If we add 2/8+3/8 we get 5/8 and we need 3/8 to get a whole number so we subtract 5/8-8/8 we get 3/8 sorry if that didn't make sense
8x + 6y = 10 ----------- (1)
5x - 3y = 2.2 ---------- (2)
(2) x 2:
10 x - 6y = 4.4 --------(2a)
(2a) + (1)
18x = 14.4
x = 1.8 ------- sub into (1)
8 (1.8) + 6y = 10
14.4 + 6y = 10
6y = 10 - 14.4
6y = - 4.4
y = - 0.73
There is 1 set of solution to it. (Answer C)
(-2,-4)
Cramer's rule
10x - 4y = -4
-3x + 7y = -22
Main determinant : 58
Determinant of <em>x</em> : -116
Determinant of <em>y</em> : -232
So, (-2,-4)
Hope this helps and please consider marking branliest.
