Given Equation:-
- 5x+y=17 . . . . . . . . 1
- x+y=3 . . . . . . . . . . 2
To find :
Solution :
Let's start with equation 2:-
x + y = 3
y = 3 - x
Put the value of y in Equation 1
- 5x+y=17
- 5x + (3 - x) = 17
- 5x - x + 3 = 17
- 4x + 3 = 17
- 4x = 17 - 3
- 4x = 14
- x = 14/4
- x = 7/2
- x = 3.5
Now Let's find value of y:
put the value of x in equation 2:
y = 3 - x
y = 3 - 3.5
y = 0.5
