Question

If 2x − 3y = 5 3x − 2y = 10 and , then find the value of x − y

Answer 1

$\sf \pmb{Answer :}$

Step-by-step explanation:

3x+2y =5      (1)

2x-3y = 10     (2)

add both the equation:

5x-y =15     (3)

now subtract the equatoin (2) from(1):

x+5y = -5      (4)

now multiply eq.(3) from 5.

25x-5y =75            (5)

now add eq (4) and (5):

26x =70

x=70/26=35/13

y = -5-x/5

y=  -5 - 35/13 *5

y= -5 -7/13

y= -72/13

x+y = 35/13+ (- 72/13)

=35-72/13   =  -37/13

x-y = 35/13 - (-72/13)

      =  35+72/13    =  107/13
