Question

решите уравнение 3х+2=0
3-5х=0
0.6х+1.8=0
7-0.7=0 помогите надо очень срочно

Answer 1

решение на фото приведено

Answer 2

$3 - 5x = 0 \\ 5x = 3 - 0 \\ 5x = 3 \\ x = \frac{3}{5}$
$0.6x + 1.8 = 0 \\ 0.6x = 0 - 1.8 \\ 0.6x = - 1.8 \\ x = - 3$
$7 - 0.7 x= 0 \\ \\ 0.7x = 7 \\ x = 10$
$3x + 2 = 0 \\ 3x = - 2 \\ x = - \frac{2}{3}$
