Question

find (x+y) by (x-y) if:
x=2/3 , y=3/2

Answer 1

Answer:

-13/5

Step-by-step explanation:

(2/3 + 3/2) ÷ (2/3 - 3/2)

(4/6 + 9/6) ÷ (4/6 - 9/6)

13/6 ÷ -5/6

13/6 × -6/5

= -13/5

Answer 2

Concept:

Mathematics has 4 basic operations namely edition subtraction multiplication and division. Simplifying and expression means solving the expression to reduce it into its lowest form. Expanding and expression means to apply all the operations of mathematics and make a simple expression.

Given:

We are given that:

x = 2 / 3 and y = 3 / 2.

Find:

We need to find that:

( x + y ) ÷ ( x - y )

Solution:

We will find the value by substituting the given values in the expression:

( x + y ) ÷ ( x - y )

x = 2 / 3 and y = 3 / 2

= ( 2 / 3 + 3 / 2 ) ÷ ( 2 / 3 - 3 / 2 )

=( 13 / 6 ) ÷ ( -5 / 6 )

= 13 / ( - 5 )

= - 13 / 5.

Therefore, the value of ( x + y ) ÷ ( x - y ) is - 13 / 5.
