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