Answer:
x= -19
Step-by-step explanation:
2x-4x-9=29
-2x=29+9
x=38/-2
= -19
Answer:
y=9-7x
If x= -1, y=16
If x= 0, y=9
If x=2, y= -5
Step-by-step explanation:
Because you are solving the equation for y, you want to have y by itself on one side. The only way to do that in this problem is by subtracting the 7x on both sides.
y+7x=9
-7x -7x ---> y=9-7x
The next part of the question says to find the value of Y for each value of X. Using the given X values, we plug them into the equation we just got in order to find Y.
y=9-7(-1) ----> y=16
y=9-7(0) ----> y=9
y=9-7(2) ----> y=-5
Answer:

Answer:
x<−8 or x>−4
Step-by-step explanation:
−x>8 or −x<4
We know either −x>8 or −x<4
−x>8(Possibility 1)
−x
−1
>
8
−1
(Divide both sides by -1)
x<−8
−x<4(Possibility 2)
−x
−1
<
4
−1
(Divide both sides by -1)
x>−4
