Question

Решите уравнение :
и) -z = -8
к) 4x = 3
л) 5t = -10
м)15y = -3

Answer 1

1)z=-8:-1
z=8
2) x=3:4
x=3/4
3) t=-10:5
t=-2
4)y=-3:15
y=-1/5

Answer 2

- z = - 8
  z = 8
-------------------
4x = 3
 x = 3/4
------------------
5t = - 10
  t = - 2
------------------
15y= - 3
y = - 3/15   (сократим на 3)
y = - 1/5
