Solve the simultaneous equations x + 4y = 1 and 2x − y = 3. • We can rearrange the first equation for x and substitute into the second equation; x = 1 − 4y so 2 ... Apr 28, 2022 ... How do you solve x squared minus 2x minus 4y squared minus 4y? The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2) ... Detailed step by step solution for x-2y=1,2x-4y=2. Let second-degree equation be, ax 2 + by 2 + 2hxy + 2gx + 2fy + c = 0. Discriminant = Δ = Case: 1 If discriminant (Δ) of this equation doesn't x, = 3. The solution is thus: x = 3, y = 2. (c)z − x = 2 and 2x = −2. Solution: From: 2x = −2 we have that x = −1. Inserting this into z − x = 2 we find: z − (− ... 1 Answer. Alan P. Dec 5, 2015. (x−1)2+(y−(−2))2=(√6) ... ... 2x 8 y. 5 x. 5.
