-1,7 ∙ 16= -1,3 -7,9= –5 – (– 2) + 3= -3х +1,9 = 2х +8,4

Question

-1,7 ∙ 16=
-1,3 -7,9=
–5 – (– 2) + 3=

-3х +1,9 = 2х +8,4

Answer 1

-1.7 * 16 = -27.2
-1.3 - 7.9= - 9.2
-5 + 2 + 3 = 0
- 3x +1.9 = 2x + 8.4
-5x = 6.5
x = - 1.3

Answer 2

-1,7 ∙ 16=

27.2

-1.3 - 7.9 =

-9.2
-5-(-2)+3=

-5+2+3=

0
-3х +1,9 = 2х +8,4
-3х - 2х = -1.9+ 8.4
-5х = 6.5
-х = 1.3
х = -1.3
