Answer: y= -7
Step-by-step explanation:
First find x: y= -2x+4 so you take that and substitute it into your second equation -x+3(-2x+4)=-9 ---> -7x+12=-9 ---> -7x= 3 ---> x=-3/7
Now you can find y by substituting x: y=-2x+4 ---> y=-2(-3/7) +4 ---> y=
The missing number is 12. The sequence goes 7, 12, 17. If you subtract five from each number, you get the one before it.
Answer:
n = -19
Step-by-step explanation:
2(n+8) = n - 3
2n + 16 = n - 3
2n = n - 19
n = - 19
The line doesn’t appear to be moving, so I believe it’s just y=4.
