Answer 1

Respuesta:

12x - 2 = 5x + 12.

12x - 5x = 12 +2

7x = 14

x = 14:7

x=2

$6 \times ( {x}^{2} + 1) = 60 \\ 6 {x}^{2} + 6 = 60 \\ 6 {x}^{2} = 60 - 6 \\ 6 {x}^{2} = 54$

${x}^{2} = 54 \div 6 \\ {x}^{2} = 9 \\ x = \sqrt{9} \\ x = 3$

$\frac{1}{5}x + \frac{3}{5}x = 4 \\ \frac{4}{5}x = 4 \\ x = 4 \div \frac{4}{5} = 4 \times \frac{5}{4} \\ x = 5$
