"-3f(x) means ""the function of x"" and is another way of writing y when the variable x is an independent variable. To get f(x) on one side of the equation, do the following:9x + 3y - 9x = 12 - 9x3y = 12 - 9x3y / 3 = (12 - 9x) / 3y = 12/3 - 9x/3y = 4 - 3xy = f(x) = -3x + 4"
<h3>Given</h3>
n packages of pencils are purchased at $1.40 each
m pads of paper are purchased at $1.20 each
<h3>Find</h3>
the meaning of 1.4n
the meaning of 1.2m
the meaning of 1.4n + 1.2m
<h3>Solution</h3>
1.4n is the <em>number of dollars spent on packages of pencils</em>
1.2m is the <em>number of dollars spent on pads of paper</em>
1.4n + 1.2m is the <em>total amount spent on the supplies</em>
Add 4 of both sides leaving you with
3/2x=20
Then multiply both sides by 2/3 giving you x=3
