Step-by-step explanation:
2x+5y=9. equation 1
x+y=3. equation 2
put x=3-y in equation 1
2x+5y=9
2(3-y)+5y=9
6-2y+5y=9
3y=9-6
3y=3
y=3/3
y=1
x=3-y
x=3-1
x=2

_________________________
- x and y value
From Equation (1) ➩
Puting x value in Equation (2) ➩
Puting y value in Equation (3) ➩
============================================
Verification ➥
( Puting x,y value in Both Equation )
We Found,
Both Equation Follow L.H.S = R.H.S So x,y value is Correct
