Answer 1

$(0,5x - 3,7 \ \cdotp 2,4): 2,1 \ \cdotp 100 : 3,4 =0$

$\bigg (\dfrac{1}{2}x - 8,88 \bigg) : \dfrac{21}{10} \ \cdotp 100 : \dfrac{17}{5} = 0$

$\bigg (\dfrac{1}{2}x - \dfrac{222}{25} \bigg) : \dfrac{21}{10} \ \cdotp 100 \ \cdotp \dfrac{5}{17} = 0$

$\bigg (\dfrac{1}{2}x - \dfrac{222}{25} \bigg) \ \cdotp \dfrac{5000}{357} = 0$

$\dfrac{2500}{357}x - \dfrac{14800}{119} = 0$

$2500x - 44400 = 0$

$2500x = 44400$

$x = \dfrac{44400}{2500} = \dfrac{444}{25} = 17\dfrac{19}{25} = 17,76$

Answer 2

1) 3,7×2,4=8,88
2) (1/2х-222/25)÷10/21×100/23=0
3) (1/2х-222/25)÷500/357=0
4) 250/357х-1480/119=0
5) 250х-4440=0
6) х=444/25=17,76
