Now that that's done, we'll be performing two operations on both sides. The operation we'll want to do is subtracting both sides of the equation by 53. We do this to get x on its own.
<em>Original Equation :</em> x + 53 = 15
<em>New Equation {Added Subtract 53 to Both Sides} :</em> x + 53 - 53 = 15 - 53
Now we have to solve the equation. Let's do the left side first.
<em>Left Side of the Equation :</em> x + 53 - 53
<em>Left Side of the Equation {Solved} :</em> x
Now, we'll solve the right side of the equation.
<em>Right Side of the Equation :</em> 15 - 53
<em>Right Side of the Equation {Solved} :</em> -38
Now we can put both solutions to both sides of the equation together.
<em>New Equation :</em> x = -38
Since this cannot be simplified any farther, this is our final answer. And that's it!
<em>So, now we know that in the equation x + 53 = 15,</em> x = -38
Step-by-step explanation: So if the double pack of CD's is 20 dollars and that $4 less than 3/4 of the triple pack, then $20 + $4 = $24, then to find how much 1/4 of the cost is we divide 24 by 3, getting $8. Finally we multiple $8 by 4 to get $32, so the cost for a triple pack is $32.
