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

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

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
