Answer:

The first term is 14.

Step-by-step explanation:

The general formula for this kind of sequence (arithmetic) is a(n) = a(1) + (n-1)c, where c is the common difference.  Here, we have a(6) = -1 = a(1) + (6-1)(-3), or -1 +15 = a(1).  The first term is 14.

-6x + 3y = 9<br>10x + 4y = -6<br>​
Stells [14]

Step-by-step explanation:

(-6x +3y=9 )×4

( 10x+4y)×3

-24x +12y =36

30x+12y= -18

-24x+12y- (30x+12y)= 36-(-18)

-54x = 54

x= -1

by using 10x +4y = -6

apply x= -1

-10+4y= -6

4y= -6 +10

4y=4

y=1

so the answer is x=-1 and y= 1
