Question

3ײ-9=39 resolver por el método de despeje​

Answer 1

Respuesta:

X = 4 y -4

Explicación paso a paso:

3ײ-9=39

3ײ = 39 + 9

3ײ = 48

ײ = 48/3

ײ = 16

$x= \sqrt{16}$

x = +-4

X = 4 y x = -4

Answer 2

$3x {}^{2} = 39 + 9 \\ 3x {}^{2} = 48 \\ x {}^{2} = 48 \div 3 \\ \\ x {}^{2} = 16 \\ x = \sqrt{16} \\ x = 4$
