2 consecutive positive integers....x and x + 1
" the product " means multiply and " the sum " means add
x(x + 1) = x + (x + 1) + 1
x^2 + x = 2x + 2
x^2 - 2x + x - 2 = 0
x^2 - x - 2 = 0
(x + 1)(x - 2) = 0
x + 1 = 0
x = -1......not this one because it is negative
x - 2 = 0
x = 2
x + 1 = 2 + 1 = 3
so ur numbers are : 2 and 3 <==

Remove the parentheses, move the terms, collect like terms,calculate, divide both sides

869 * .08 = 69.52
69.52 + 869 = 938.52
938.52- 75 = 863.52
