The correct question is
<span>The product of two consecutive positive integers is
11 more than their sum. find the integers.
Let
x-------> the first </span>positive integer
x+1-----> the second consecutive positive integer
we know that
x*(x+1)=11+(x+(x+1))----> x²+x=11+(2x+1)----> x²+x=2x+12
x²-x-12=0
using a graph tool------> to resolve the second order equation
see the attached figure
the solution is
x=4
therefore
the numbers are
x=4
x+1=5
the answer isthe numbers are 4 and 5
5x + 15y = 1200. x. | y
___________
105 | 45
30. | 100
60. | 60
5(x) + 15y = 1200. 5(x) + 15y = 1200. 5(x) + 15y = 1200.
5(x) + 15(45) = 1200. 5(30) + 15y = 1200. 5(x) + 15(60) = 1200
5x + 675= 1200. 150 + 15y = 1200. 5x + 900 = 1200
5x = 1200 - 675 15y = 1200 - 150. 5x = 1200-900
5x = 525 15y = 1050. 5x = 300
x= 525÷5. y= 1050÷15. x = 300÷5
x= 105. y = 100 x = 60
