Step 1: Simplify both sides of the equation.
3(x−3)+5=3x+1+4
(3)(x)+(3)(−3)+5=3x+1+4(Distribute)
3x+−9+5=3x+1+4
(3x)+(−9+5)=(3x)+(1+4)(Combine Like Terms)
3x+−4=3x+5
3x−4=3x+5
Step 2: Subtract 3x from both sides.
3x−4−3x=3x+5−3x
−4=5
Step 3: Add 4 to both sides.
−4+4=5+4
0=9

Answer:

Step-by-step explanation:
Given


Required
The cost of units used
First, calculate the number of units used.



Next, multiply the units used by the cost per units,
Since the cost per unit is not given, we assume that it is x.
So, the total cost is:
