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 =
⇒ 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
