Solve the equation:
two times n plus twenty-eight equals ninety-six.

2n + 28 = 96 [Two times n plus twenty-eight equals ninety-six.}

You need to get n by itself, so you first subtract 28 on both sides

2n + 28 - 28 = 96 - 28

2n = 68    Divide 2 on both sides

n = 34

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 !
