The answer is x = -2 and y = 2.
Explanation:
- The first equation can be written as x - y = -4
- The second equation can be written as 2x + y = -2
step 1 :
Solving by elimination method to find the value of x and y,
x - y = -4
2x + y = -2
3x = -6
step 2 :
x = -6/3 = -2
The value of x is x = -2
step 3 :
Substitute x = -2 in any of the given equations.
⇒ y = x + 4
⇒ y = -2 + 4
⇒ y = 2
