<em>let</em><em> </em><em>the</em><em> </em><em>cost</em><em> </em><em>price</em><em> </em><em>=</em><em> </em><em>5</em><em>x</em>

<em>let</em><em> </em><em>the</em><em> </em><em>selling</em><em> </em><em>price</em><em> </em><em>=</em><em> </em><em>7</em><em>x</em>

<em>profit</em><em> </em><em>=</em><em> </em><em>selling</em><em> </em><em>price</em><em> </em><em>-</em><em> </em><em>cost</em><em> </em><em>price</em>

<em>=</em><em> </em><em>7</em><em>x</em><em> </em><em>-</em><em> </em><em>5</em><em>x</em><em> </em>

<em>=</em><em> </em><em>2</em><em>x</em>

<em>profit</em><em> </em><em>percentage</em><em> </em><em>=</em><em> </em><em>2</em><em>x</em><em>/</em><em>5</em><em>x</em><em> </em><em>×</em><em> </em><em>1</em><em>0</em><em>0</em>

<em>=</em><em> </em><em>2</em><em>×</em><em>2</em><em>0</em>

<em>=</em><em> </em><em>4</em><em>0</em><em> </em><em>percent</em>

The sum of two numbers is 139 and the difference is 53. Explain how to find the two numbers.
Airida [17]

Answer:

43 & 96

Step-by-step explanation:

x=one number

y=other number

x+y=139

x-y=53     x=y+53

substitute for x

y+53+y=139

reduce

2y+53-53=139-53

2y=86

2y/2=86/2

y=43

x=96
