• 4x² + y² = 40
• (2x)² + y² + 2*2x*y - 2*2x*y = 40
• (2x + y)² - 4xy = 40
• (2x + y)² - 24 = 40
• 2x + y = √64
• 2x + y = 8

• 17 - 17x - 5x - 60 = 8 - 56x
• -43 - 22x = 8 - 56x
• 34x = 51
• x = 51/34 = 3/2

I skip some steps because I am very lazy. But you will definitely understand the answer because you're smart, aren't you .
