Question

a) x-14=-30
b) -15-x=2
c) x:(-3)=-4
d) 3x+5=-16
e) x+15=-6

Answer 1

a) x-14=-30
x=-30+14
x= -16

b)-15-x=2/+15
-x= 2+15
-x= 17/•(-1)
x= -17

c) x:(-3)=-4/•(-3)
x = -4•(-3)
x=12

d) 3x+5= -16/-5
3x= -16-5
3x= -21/:3
x = -21:3
x= -7

e) x+15= -6/-15
x= -6-15
X= -21

Answer 2

Răspuns:

• a) x = -16
• b) x = -17
• c) x = 12
• d) x = -7
• e) x = -21

Explicație pas cu pas:

❁ Salut! ❁

a) x - 14 = -30

x = -30 + 14

x = -16

b) -15 - x = 2

-x + (-15) = 2

-x - 15 = 2

-x = 2 + 15

x = -17

c) x : (-3) = -4

x = -4 × (-3)

x = 12

d) 3x + 5 = -16

3x = -16 - 5

3x = -21

x = -21 ÷ 3

x = -7

e) x + 15 = -6

x = -6 - 15

x = -21

Succes! ☺️
