Question

Решите уравнения умоляю пж


1) -0,01*x=1


3) |x+1|=3


4)-12/x= -8,4/-6,3

Answer 1

1)

$- 0.01 \times x = 1 \\ x = 1 \div ( - 0.01) \\ x = - 100$

3)

$|x + 1| = 3 \\ |x| = 2 \\ x = 2$

4)

$\frac{ - 12}{x} = \frac{ - 8.4}{ - 6.3} \\ x = ( (- 12) \times (- 6.3)) \div ( - 8.4 ) \\ x = - 9$
