Question

if 2x+3y=5 and 3x+2y=10. find x-y.​

Answer 1

$\huge\bold{Solution}$

_____________________________

_____________________________

2x + 3y = 5 ....(1)

3x + 2y = 10.....(2)

Multiply equation 1 by 2 and multiply equation 2 by 3

we get,

4x + 6y = 10...(1.1)

9x + 6y = 30 ....(2.1)

from equation (1.1) and (2.1) we get,

-5x = -20

x = $\dfrac{20}{5}$

x = 4

put the value of x in equation (1.1) we get,

4 × 5 + 6y = 10

20 + 6y = 10

6y = -10

y = $\dfrac{-10}{6}$ = $\dfrac{-5}{3}$

=> x - y

= 5 - $\dfrac{-5}{3}$

= 5 + $\dfrac{5}{3}$

= $\dfrac{15 + 5}{3}$

= $\dfrac{20}{3}$
