8 - 3x = 6

=> 3x = 2

=> x = \(\frac{2}{3}\)

Chứng minh các đẳng thức sau xác định với mọi giá trị của t

C = \(\frac{\left|2-3t\right|}{2t^2+4t+5}\) + \(\frac{t-1}{2}\)

D = \(\frac{t+1}{3t^2-t+1}\) - \(\frac{2t^2-3}{3}\)

Người có bản lĩnh sống là người dù trong hoàn cảnh nào cũng bình tĩnh, kiên cường, nỗ lực hết sức mình để chèo lái con thuyền của đời mình đi đúng hướng, đi theo con đường tích cực, đúng pháp luật, chuẩn mực đạo đức, chứ không buông xuôi, bỏ mặc cho muốn ra sao thì ra, hoặc thỏa hiệp với cái xấu, cái ác để tìm lối thoát cho riêng mình còn mặc kệ người khác chịu thiệt thòi cay đắng.
