Question

1)4х=112х+6
2) 1/2=45х+5х (/-ДРОБЬ!)
3) 0,5=1,5+3,5х

Answer 1

$1) \: 4x = 112x + 6 \\ 4x - 112x = 6 \\ - 108x = 6 \\ x = - \frac{1}{18}$

$2) \: \frac{1}{2} = 45x + 5x \\ \frac{1}{2} = 50x \\ 50x = \frac{1}{2} \\ x = \frac{1}{100}$

$3) \: 0.5 = 1.5 + 3.5x \\ - 3.5x = 1.5 - 0.5 \\ - 3.5x = 1 \\ x = - \frac{2}{7}$
