Answer:
x = 7/3
y = 1/3
Step-by-step explanation:
y = x - 2.... (1)
2x + y = 5.... (2)
Rearranging equation (2), we have
y = -2x +5 .... (3)
Let's multiply equation (1) by 2 so that we can easily simplify by substitution.
Therefore, it becomes 2y = 2x - 4 ... (4)
We add equation (3) and (4)
3y = 1
y= 1/3
Now, substitute (y= 1/3) in equation 1
It becomes:
1/3 = x - 2
x = 1/3 + 2
Simplifying with a LCM of 3
x = (1 plus 6, all over 3)
= 1+6/ 3
= 7/3
