Question

alguien me ayuda xfa ​

Answer 1

Respuesta:

$x + \frac{10}{5} + 7 = 20 \\ x + 2 + 7 = 20 \\ x = 20 - 9 \\ x = 11$

$\frac{x}{7} + 10 = 20 \\ \frac{x}{7} = 20 - 10 \\ \frac{x}{7} = 10 \\ x = 70$

$6(x + 5) = 54 \\ 6x + 30 = 54 \\ 6x = 54 - 30 \\ 6x = 24 \\ x = \frac{24}{6} \\ x = 4$

$2x^{3} + 1 = 17 \\ 2 {x}^{3} = 17 - 1 \\ 2 {x}^{3} = 16 \\ {x}^{3} = \frac{16}{2} \\ {x}^{3} = 8 \\ x = \sqrt[3]{8} \\ x = 2$

$\sqrt{3x - 5} = 4 \\ 3x - 5 = {4}^{2} \\ 3x = 16 + 5 \\ x = \frac{21}{3} \\ x = 7$

$\sqrt{4x} + 1 = 3 \\ \sqrt{4x} = 3 - 1 \\ \sqrt{4x} = 2 \\ 4x = {2}^{2} \\ x = \frac{4}{4} \\ x = 1$

$(x - 4)^{3} = 1 \\ x - 4 = \sqrt[3]{1} \\ x = 1 + 4 \\ x = 5$

$2x + 4 = x + 12 \\ 2x - x = 12 - 4 \\ x = 8$
