Answer:
one solution
Step-by-step explanation:
There will be one solution if the left-side x-coefficient is different from the right-side x-coefficient.
Simplifying, we get ...
x + 1/2x -2 = 1/2x +6x -12
3/2x -2 = 13/2x -12
The left-side coefficient is 3/2, which is different from the right-side coefficient of 13/2. The equation will have one solution.
__
Add 12-3/2x to both sides to get ...
10 = 5x
2 = x . . . . . divide both sides by 5. This is the solution.
x = number of miles you walk
5*x = amount of money the cousin donates
25 = amount of money your friend donates
5x+25 = total amount of money donated
y = total amount of money donated
y = 5x+25
Answer: y = 5x+25
Distribute: 18x-36 = 8x + 18 -2x
Simplify: 18x-36 = 6x + 18
Add 36: 18x = 6x+54
Subtract 6x: 12x = 54
Divide: x = 4.5
