Answer:
x = 1/3
There is one solution
Step-by-step explanation:
3x -1= 1-3x
Add 3x to each side
3x+3x -1= 1-3x+3x
6x-1 =1
Add 1 to each ide
6x-1+1 = 1+1
6x =2
Divide each side by 6
6x/6 = 2/6
x = 1/3
There is one solution

Answer: Peters age is 25 years old.
The two equations that can be written given the information are:
h = x/5 + 7 and 4h = 2x - 2
When x = Peter's age and h = Phil's age.
If we use substitution, we can come up with the equation:
4(x/5 + 7)= 2x - 2
4x/5 + 28 = 2x - 2
4x + 140 = 10x - 10
150 = 6x
25 = x
Solving this for x, we give us that Peter's age is 25.
