2) |x - 3|= 11;
3) - 48 : (x + 18)= - 16.
помогите пожалуйста срочно!!!!! ​

Answer 1

Відповідь:

1) -9(x - 4) = 72

-9x + 36 = 72

-9x = 72 - 36

-9x = 36

x = 36 / -9

x = -4

2)|x - 3| = 11

x - 3 = 11

x = 11 + 3

x = 14

x - 3 = -11

x = -11 + 3

x = -8

3)-48 / (x + 18) = -16

-48 = -16(x + 18)

-48 = -16x - 288

-48 + 288 = -16x

240 = -16x

x = 240 / -16

x = -15
