Question

gente me ajuda
-x=-2
-7x=14
-3x=10
-5x=-12
-4x=8
-3x=-9
-5x=15
-2x=-10
15=-3x
-40=5x

Answer 1

Vamos lá:
-x=-2 .(-1)
X = 2

-7x=14 .(-1)
7x = -14
x = -14 ÷ 7
x = -2

-3x=10 .(-1)
3x = -10
x = - 10/3

-5x=-12 .(-1)
5x = 12
x = 12/5

-4x=8 .(-1)
4x = -8
x = -8÷4
x = -2

-3x=-9 .(-1)
3x = 9
x = 9÷3
x = 3

-5x=15 .(-1)
5x = -15
x = -15 ÷ 5
X = -3

-2x=-10 .(-1)
2x = 10
x = 10÷2
x = 5

15=-3x .(-1)
-15 = 3x
3x = -15
x = -15 ÷ 3
x = -5

-40=5x
5x = -40
x = -40 ÷ 5
x = -8

Espero ter ajudado !
