Answer:

x = 6  

y = 4

Step-by-step explanation:

2x - 2y - 4 = 0,  3x - 4y - 2 = 0​

Let's Use the substitution method...

2x - 2y - 4 = 0

⇒ 2x - 2y = 4

⇒ 2(x - y) = 4

⇒ x - y = \frac{4}{2}

⇒ x - y = 2

x = 2 + y                                       ···(1)

3x - 4y - 2 = 0​

⇒ 3x - 4y = 2

⇒ 3 (2 + y) - 4y = 2

⇒ 6 + 3y - 4y = 2

⇒ 6 + (-y) = 2

⇒ -y = 2 - 6

⇒ -y = -4

y = 4                                             ···(2)

Now, by using eqⁿ (1) & (2), We get:

x = 2 + 4 = 6

x = 6
