Heya
Here is ur answer
========================
Given equations :-
X + Y = 5 --------(1)
2x - 3y = 4 ------(2)
From equation (1)
X + y = 5
X = 5-y
Now v got X value
So ,
Substitute value of "X " in equation (2)
♦ 2x -3y = 4
♦ 2 (5-y ) - 3y = 4
♦ 10 - 2y -3y = 4
♦ 10 - 5y = 4
♦ -5y = 4 -10
♦ y = 6/5
Substitute y value in equation (1)
X + (6/5) = 5
X + 6/5 = 5
X = 5 -6/5
X = 19 / 5
____
Hence
X = 19/5, y = 6/5
=======================
Hope it helps u..!!

Step-by-step explanation:
x=5-y
x=5
put x=5 in equation 2
2(5)-3y=4
10-3y=4
8y=4
y=4/8
now y=4/8 in equation 2
2x-3(4/8)=4
2x-3/1(4/8)=4
2x-12/8=4
x=-12/8-4/2
x=48/16
