⇒4x-3y=-1---(2)

Adding (1) and (2),

2x+y=7

+ 4x-3y=-1

⇒6x-2y=6

⇒2(3x-y)=6

⇒3x-y=3-----(3)

Adding (1) and (3),

2x+y=7

+3x-y=3

⇒5x=10

⇒x=10/5

⇒

**x=2**

Substituting 'x' in (1),

2(2)+y=7

⇒4+y=7

⇒y=7-4

⇒

**y=3**

4x - 3y + 1 = 0 or 4x - 3y = -1 equation [2]

Multiply eq [1] by 2 and eq [2] by 1 we get,

4x + 2y = 14

4x - 3y = -1

___________

2y + 3y = 14 + 1

⇒5y = 15

⇒ y = 15/5

⇒y = 3

Putting the value of y in eq [1] we get,

2x + y = 7

⇒ 2x + 3 = 7 (since y = 3)

⇒2x = 7 - 3

⇒ 2x = 4

⇒ x = 4/2

⇒ x = 2

Answer

**x = 2**

**y = 3**
