(-5,1) and (-10,2) are two pairs of integer such that a/b = -5.
Given :
a/b = -5
To Find :
Any two Pairs of integer to satisfy the given equation
Solution:
a/b = -5
⇒ a = -5*b
The given equation has two variables with each having degree one. Therefore it is known as a linear equation of two variables. By assuming one of the values of the above equation, we can get the value of another variable by substituting the assumed variable.
put b =1
⇒ a = -5 *1
⇒ a = -5
∴(-5,1)
Similarly, put b = 2
⇒ a = -5 *2
⇒ a = -10
∴(-10,2)
∴ (-5,1) and (-10,2) are two pairs of integer such that a/b = -5.
