Answer:
x = 45
Step-by-step explanation:
Given
= 9

3x=24
x=8
Answer:
940 grams
Step-by-step explanation:
Answer:
(Down Below)
Step-by-step explanation:
Plug in the value of x in the left column for all the values in the equation. I will do a couple for you.
Since -4 is the value of x, substitute it into the equation for x.
![y= -4-5=-9](https://tex.z-dn.net/?f=y%3D%20-4-5%3D-9)
-1
![y=-1-5=-6](https://tex.z-dn.net/?f=y%3D-1-5%3D-6)
0
![y=0-5=-5](https://tex.z-dn.net/?f=y%3D0-5%3D-5)
You can do the rest. You got this! Comment if you need more help!
3x + 4y = 31
2x - 4y = -6
*The +4 and -4 in the center of the equation cancel out because 4-4 = 0*
3x = 31
2x = -6
------------
*add like terms*
3x + 2x = 5x
31 - 6 = 25
So now you should have this written on your paper ... > 5x = 25
*Divide by 5 on each side*
5x = 25

5 5
x = 5
