How to solve Two-Step Equations?
Two-step equations involve two math operations - one operation is addition or subtraction. The second operation is multiplication or division.
To solve a two-step equation, follow the order of operations backwards - add or subtract, then multiply or divide to solve for x.
Example 1: Solve for x.2x-1=3 2x-1+1=3+1 First we add 1 to both sides of the equation.2x=4 2x/2=4/2 Now we divide both sides of the equation by 2.x=2
Example 2: Solve for x.x/2 +1=7 x/2+1-1=7-1 First we subtract 1 from both sides of the equation.x/2 =6 2.x/2=2.6 Now we multiply both sides of the equation by 2.x=12
Solve 4 cos(t )= 3 on[-8,10]. Solution : Here the first step is identical to the problems in the previous section. First we need to isolate the cosine on one side by itself & t
A farmer grows apples on her 400-acre farm and must cope with occasional infestations of worms. If she refrains from using pesticides, she can get a premium for "organically grown"
Let a 0 , a 1 ::: be the series recursively defined by a 0 = 1, and an = 3 + a n-1 for n ≥ 1. (a) Compute a 1 , a 2 , a 3 and a 4 . (b) Compute a formula for an, n ≥ 0.
Determine the domain of each of the following functions. f( x ) = x - 4 / x 2 - 2 x -15 Solution With this problem we have to avoid division by
If you find nothing out of this rapid review of linear algebra you should get this section. Without this section you will not be capable to do any of the differential equations wo
In this theorem we identify that for a specified differential equation a set of fundamental solutions will exist. Consider the differential equation y′′ + p (t ) y′ + q (t
It is a fairly short section. It's real purpose is to acknowledge that the exponent properties work for any exponent. We've already used them on integer and rational exponents al
