Given : 3x - 2y = 5 ---- (1)
Given : 3y - 2x = 3 = > -2x + 3y = 3 ----- (2)
On solving (1) * 2 & (2) * , we get
⇒ 6x - 4y = 10
⇒ -6x + 9y = 9
----------------
5y = 19
y = 19/5.
Substitute y = 19/5 in (1), we get
⇒ 3x - 2y = 5
⇒ 3x - 2(19/5) = 5
⇒ 3x - 38/5 =5
⇒ 15x - 38 = 25
⇒ 15x = 63
⇒ x = 63/15
⇒ x = 21/5.
Therefore, the value of x = 21/5 and y = 19/5.
Hope this helps!

Hey Mate ⭐✋⭐
Here's ur answer ⤵
Solve for x in 3x-2y=5
x= 5+2y/3
Substitute x= 5+2y/3 into 3y-2x=3
3y-2(5+2y)/3=3
Solve for y in 3y-2(5+2y)/3=3
Y= 19/5
Substitute y=19/5 into x=5+2y/3
x=21/5
Therefore,
x=21/5
y=19/5
Hope it helps you! ヅ
