The sum of x and y decreased by their product is (x + y)- xy.
y-8
17 - y
y = 125 - x
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
The sum of x and y decreased by their product is (x + y)- xy.
y-8
y-6
17 - y
2780 decreased by 10% = 90% of 2780 = 2780*90/100 = 2502
6x - (6 + y)
The expression is: 2y -20
The value of y increases, such that x*y remains a constant.
There is insufficient information for us to even begin to understand this question. Please edit the question to include more context or relevant information. There is something missing in "... half the sum of [???] and y decreased ...".
5(x^2 + y)
Ten cuidado y adiós.
