Question

Помогите решить уравнения
-3х+9=0
-5х+6=0
5х-3= -10х
х+9= - 9х

Answer 1

1.
$- 3x + 9 = 0 \\ - 3x = 9 \\ x = 9 \div ( - 3) \\ x = - 3$
2.
$- 5x + 6 = 0 \\ - 5x = - 6 \\ x = ( - 6) \div ( - 5) \\ x = 1.2$
3.
$5x - 3 = - 10x \\ 5x + 10x = 3 \\ 15x = 3 \\ x = 3 \div 15 \\ x = 0.2$
4.
$x + 9 = - 9x \\ x + 9x = - 9 \\ 10x = - 9 \\ x = ( - 9) \div 10 \\ x = - 0.9$
Удачи))))

Answer 2

$- 3x + 9 = 0 \\ 3x = 9 \\ x = 9 \div 3 \\ x = 3$
$- 5x + 6 = 0 \\ 5x = 6 \\ x = 6 \div 5 \\ x = 1.2$
$5x - 3 = - 10x \\ 5x + 10x = 3 \\ 15x = 3 \\ x = 3 \div 15 \\ x = 0.2$
$x + 9 = - 9x \\ x + 9x = - 9 \\ 10x = - 9 \\ x = - 9 \div 10 \\ x = - 0.9$
