Answer:
3x
Step-by-step explanation:
-(x-1) +5 = 2(x+3) - c
C is the unknown term
Distribute the negative sign and the 2
-x+1 +5 = 2x+6 -c
Combine like terms
-x+6 = 2x +6-c
Solve for c
Add x to each side
-x+x +6 = 2x+x +6-c
6 = 3x+6 -c
Add c to each side
6+c = 3x +6 -c+c
c+6 = 3x+6
Subtract 6 from each side
c+6-6 = 3x+6-6
c = 3x
When c = 3x, the two sides of the equation are equal, and the solutions are infinite.
Answer:36
Step-by-step explanation: first I did
9÷5=1.80 per box.
so then I did 1.80 x 20 which = 36

Answer:
The sum of all the possible values for z that satisfy the above equation is -5.
Step-by-step explanation:
The given equation is
![\frac{5}{z}-\frac{2z+4}{z+2}=-3](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7Bz%7D-%5Cfrac%7B2z%2B4%7D%7Bz%2B2%7D%3D-3)
We need to find the sum of all the possible values for z that satisfy the above equation.
The given equation can be rewritten as
![\frac{5}{z}-\frac{2(z+2)}{z+2}=-3](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7Bz%7D-%5Cfrac%7B2%28z%2B2%29%7D%7Bz%2B2%7D%3D-3)
Cancel out common factors.
![\frac{5}{z}-2=-3](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7Bz%7D-2%3D-3)
Add 2 on both sides.
![\frac{5}{z}-2+2=-3+2](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7Bz%7D-2%2B2%3D-3%2B2)
![\frac{5}{z}=-1](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7Bz%7D%3D-1)
![5=-z](https://tex.z-dn.net/?f=5%3D-z)
Multiply both sides by -1.
![-5=z](https://tex.z-dn.net/?f=-5%3Dz)
Only z=-5 satisfy the given equation.
Therefore the sum of all the possible values for z that satisfy the above equation is -5.
