Question

Y = X + 4 Y = -2x -2

Answer 1

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
