Answer 2

Answer:

x = -1 and y = 2

Step-by-step explanation:

Solution;

Given;

x - y = -3................(i)

2x + 3y = 4.................(ii)

Multiplying (i) by 3, we get,

3x - 3y = -9.................(iii)

Adding (ii) and (iii)

2x + 3y = 4

3x - 3y = -9

5x = -5

5x = -5

or, x = -5/5

or, x = -1

Putting x = -1 in (i), we get,

x - y = -3

or, -1 - y = -3

or, -1 +3 = y

or, y = 2
