math question

Note: the absolute value of X will be denoted abs(X)

1. Complete the principles for solving absolute - value problems:

X is an algebraic expression and P is a nonnegative real number,

A) The solutions of abs(X) = P are those that satisfy ???

B) abs(X) < P is equivalent to  ???

C) abs(X) > P is equivalent to ???

D) solve: abs(2x-3) < 5

2. Describe the technique used to solve a formula for a specified letter when the formula contains more than one term with that variable.

Solve the following for w to illustrate the technique(explain/describe each step):

ax - b + cw = dw + f
