Question

hallar el balor de x
con operacion.
cuanto es
5(5-x)=15
3(x-6)=-5(2-x)
1 - 2(x-2 )= 3(2-x)
5x = -100

Answer 1

Explicación paso a paso:

$5(5-x)=15 \\ \\ 25 - 5x = 15 \\ \\ - 5x = 15 - 25 \\ \\ - 5x = - 10 \\ \\ x = \frac{ - 10}{ - 5} \\ \\ x = 2$

------------------------------------------------------------------------------------------

$3(x-6)=-5(2-x) \\ \\ 3x - 18 = - 10 + x \\ \\ 3x - x = - 10 + 18 \\ \\ 2x = 8 \\ \\ x = \frac{8}{2} \\ \\ x = 4$

------------------------------------------------------------------------------------------

$1 - 2(x-2 )= 3(2-x) \\ \\ 1 - 2x + 4 = 6 - 3x \\ \\ - 2x + 3x = 6 - 4 - 1 \\ \\ x = 1$

------------------------------------------------------------------------------------------

$5x - 100 \\ \\ x = \frac{ - 100}{5} \\ \\ x = - 20$
