When an equality is set up like this you are going to have 2 answers
Original inequality: <span>-3 ≤ 5 – 2v < 7
</span><span>When you solve this problem, solve it by making two equations
You will reuse 5-2v in both equation
-3 </span>≤ 5-2v
&
5-2v < 7
now do simple math
-3 ≤ 5-2v
-8 ≤ -2v
4 ≤ v
however when you divide when you divide by a negative number for an inquality you MUST change the sign to its opposite so
4 ≤ v will be 4≥ v
5-2v < 7
-2v < 2
v < -1
since we divide by a negative in order to get the variable by itself we change the sign to its opposite
v < -1 becomes v > -1

<h2>
<em>step</em><em> </em><em>1</em><em> </em><em>:</em><em>study</em><em> </em><em>the</em><em> </em><em>problem</em><em> </em></h2>
<em>write</em><em> </em><em>down</em><em> </em><em>your</em><em> </em><em>fact</em><em> </em><em>or</em><em> </em><em>what</em><em> </em><em>you</em><em> </em><em>know</em><em> </em><em>about</em><em> </em><em>the</em><em> </em><em>problem</em><em>. </em><em>also</em><em> </em><em>crossout</em><em> </em><em>unnecessary</em><em> </em><em>parts</em><em> </em><em>of</em><em> </em><em>the problem</em><em> </em><em>and</em><em> </em><em>highlight</em><em> </em><em>important</em><em> </em><em>information</em><em>.</em>
example: X = hours
<h2> </h2><h2>Step 2: organize your facts</h2>
organize your facts means put in order ,write what it means etc.
example: the problem say rebbeca has 3 3 times as much candy than Sara. what does the problem mean ?
<h2>Step 3 : line up your strategy. </h2><h3> what are your plans for solving this problem ? what operation will u do ? how much step is in this problem ? does this make sense ? in line up your strategy u have to think about why I'm doing this? how I will do this etc.</h3>
<h2>Step 4 : validate </h2>
<h3>"SOLVE THE PROBLEM"!</h3>
Answer:
(p^2) + 3p - 18
Step-by-step explanation:
Have a nice day!
p = a + b + c
...subtract a and b
p - a - b = c
in abc order, c = -a - b + p
