Answer 2

Answer:

$x = \frac{ + 5}{7}$

$x = 1$

$x = \frac{ + 5}{1}$

Step-by-step explanation:

$(1) \geqslant \\ x = 3 + 4 \\ x = 7 \\ x = \frac{5}{7} \\ x = \frac{ + 5}{7}$

$(2) > \\ 3 {x}^{4} - 6 {x}^{3} 2 {x}^{2} - 10x - 5 \div 3 {x}^{2} - 5 \\ x = 6 - 3 \\ x = 3 \\ - 2x - 10x \\ x = 10 + 2 \\ x = 12 \\ 3x - 12 \\ x = 9 \\ x \frac{5}{5} = x = 1$

$(3) > \\ 3 {x}^{4} - 12x + 5 \div x + 1 \\ x = 12 - 3 \\ x - 9 \\ 5 \div x + 1 \\ x = \frac{ + 5}{1}$
