Answer:
A. Subtract x from both sides: (i.e. 5+x-12 = x-7 <--> 5-12 = -7)
This equation is identically true, so it holds no matter what x is.

The equation 2v-41=0 can be used to find the number of visits that would make two memberships cost the same amount.
Step-by-step explanation:
Given,
Per month charges of type 1 = $86
Per visit charge = $3
Let,
v be the number of visits.
T(v) = 3v+86
Per month charges of type 2 = $45
Per visit charge = $5
P(v) = 5v+45
For same amount to be charged;
T(v) = P(v)

The equation 2v-41=0 can be used to find the number of visits that would make two memberships cost the same amount.
Mike´s salary=x
Ron´s salary=2x
We can suggest the following equation:
x+2x=441
3x=441
x=441/3
x=147
Mike´s salary=147
Ron´s salary=2x=2(147)=294
Answer: Ron´s salary is $294 and Mike´s salry is $147.
Answer:
(3x-1) + (3x-1) + (2x+1) = 55
Step-by-step explanation:
1. 3x + 3x + 2x = 8x
2. -1 + -1 + 1 = -1
3. 8x -1 = 55
4. 8x = 55 + 1
5. 8x = 56/8
6. x = 7
