Answer:
• x = 1
• y = 0
Explanation:
Given :
- 5x - y = 5
- 3x - y = 3
To find :
- the value of x and y
Solution :
Consider,
5x - y = 5 _______(i)
3x - y = 3 _______(ii)
By using Elimination Method
on adding both the equation; we get;
5x - y = 5
3x - y = 3
_________
8x = 8
x = 1
Now on putting the value x = 1 on equation (ii); we get;
3x - y = 3
3(1) - y = 3
3 - y = 3
y = 3 - 3
y = 0
Therefore, the value of x = 1 and y = 0.

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
