Answer:
x = -4
Step-by-step explanation:
Isolate the x by substracting 2.3x from both sides, then subtract 21.6 from both sides.
After that, you will have 1.15x = -4.6. Divide both sides by 1.15 to get x = -4.

Answer:
infinite number
Step-by-step explanation:
Carry out the multiplication indicated here:
5x + 3(x-5) = 6x + 2x -15 => 5x + 3x - 15 = 6x + 2x -15
Now combine the x terms: We get 8x - 15 = 8x - 15, or -15 = -15.
This last result is always true, so this equation has an infinite number of solutions.
Answer:
The value of n in the given equation is 6
Therefore n=6
Step-by-step explanation:
Given expression is -8n+(-4n)=-72
To simplify the given expression as below :
-8n+(-4n)=-72
-8n-4n=-72
-(8n+4n)=-72
Dividing by (-) on both sides we get
8n+4n=72
12n=72 ( adding the like terms )
Dividing by 12 on both sides we get
Therefore the value of n in the given equation is 6
Therefore n=6
