Question

Find the product if the sum of two numbers is 131 and the difference is 35

Please help: this is due in one hour. Please write let statements and equations.

Answer 1

Explanation:

let the two numbers be : x and y

x +y =131 , x-y= 35

by omitting :

x+y=135

x-y=35

cancel the ys with each other and add each side together

2x=135+35 = 170

to get x

x=170/2 =85

now u have the x time to get the y u can get it for any equation u like

85+y=135

y=135-85 = 50

the product = 85 x 50 = 4250
