Step-by-step explanation:
the y axis is the same the x axis is different by 1. because 7-6= 1
Let the 2 integers be
x and
y.
Their product is 72, so we write:
xy=72. (I)
One of them, say
y, is 2 less than 5 times the other. We can write this as the equation:
y=5x-2. (II)
To find one of numbers, say x, we can substitute y with 5x-2, in the first equation:
xy=72,

expanding the left hand side expression we get:

.
