el valor de x​

Answer 1

Explicación paso a paso:

$3x + 4 = 22 \\ x = \frac{22 - 4}{3} \\ x = 6$

$5(x + 2) = 15 \\ 5x + 10 = 15 \\ x = \frac{15 - 10}{5} \\ x = 1$

$(2x + 4) \div 2 = 5 \\ 2x + 4 = 5 \times 2 \\ 2x = 10 - 4 \\ x = \frac{6}{2} \\ x = 3$

${(3x + 1)}^{2} = 49 \\ 3x + 1 = \sqrt{49} \\ 3x = 7 - 1 \\ x = \frac{6}{3} \\ x = 2$

${3x}^{2} + 2 = 14 \\ {3x}^{2} = 12 \\ {x}^{2} = \frac{12}{3} \\ {x}^{2} </p><p>= 4 \\ x = 2$

3x² + 2 = 14

3x² = 12

x² = 12/3

x² = 4

x = 2

_______________

√(x + 4) ÷ 5 = 3

(x + 4) ÷ 5 = 3²

(x + 4) = 9 × 5

x = 45 - 4

x = 41
