Multiplying by the function of -1
Answer:
the answer is there should be another digit in the quotient
2) 9=-7m+1-6
9=-7m-5
9+5=-7m
14=-7m
m=14/-7=-2
5) -36=6(2-8n)
-36/6=2-8n
-6=2-8n
-6-2=-8n
-8=-8n
n=1
Y=3x-5...(1)
5x-4y=-3...(2)
By sub. (1) into (2),we have
5x-4(3x-5)=-3
5x-12x+20=-3
-7x=-23
x=3(cor. to l d.p.)
By sub. x=3(cor. to l d.p.) into (1),we have
y=3*3-5
y=4
The solution is (3,4) (cor. to l d.p.)
