Solve the problem using Polya's step. Show your solution.. "Twice the difference of a number and 1 is 4 more than a number. Find the number.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

5+2x=a
