Question

write two pairs of integers such that a÷b =-5​

Answer 1

X +8x =900

9x=900

X=900/9

X=100

5a-a=8

4a=8

a=8/4

a=2

Answer 2

(-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.
