3x×4у = 102x-2y=2solve this equation by substitution method |
|
Answer» Answer: Explanation: By substitution method, 3 x + 4 y = 1 0 & 2 x − 2 y = 2 ⇒ 2 (x − y) = 2 ⇒ x − y = 1 ___ (2) ∴ x = y + 1 → (1). SUBSTITUTING in equation (2). ∴ 3 x + 4 y = 1 0 ⇒ 3 (y + 1) + 4 y = 1 0 ⇒ 3 y + 3 + 4 y = 1 0 ⇒ 7 y = 7 ⇒ y = 1 ∴ x = 1 + 1 x= 2 x = 2, y = 1 Hope it helps you!!!!plzz mark as brainliest.... |
