How many solutions does the system have?<br> 6x - y = -1<br> 6x+y=-1
vova2212 [387]

Answer:x=-1/6,y=0

Step-by-step explanation:

6x-y=-1....(1)

6x+y=-1...(2)

From (2) make y the subject of formula

Y=-1-6x...(3)

Substitute (3)in (1)

6x-(-1-6x)=-1

6x+1+6x=-1

Collect like terms

6x+6x=-1-1

12x=-2

X=-1/6...(4)

Substitute (4) in (3)

Y=-1-6(-1/6)

Y=-1+1

Y=0

Therefore,x=-1/6

Y=0
