Question

Determine o valor de x
A) X ÷ (-3) = -8
B) 24 = 44 - 5x
C) 8x - 32 = -40
D) 100 ÷ (-x) = +20
E) -3x - 20 = -35
F) 80 = 2x - 18

Answer 1

A) X ÷ (-3) = -8
X=-8*-3
X=24

B) 24 = 44 - 5x
-5X=24-44
-5X=-20
5X=20
X=20/5
X=4

C) 8x - 32 = -40
8X=-8
X=-1

D) 100 ÷ (-x) = +20
-20X=100
X=-5

E) -3x - 20 = -35
-3X=-15
X=5

F) 80 = 2X-18
2X=98
X=49

Answer 2

a) x = 24
b) 5 x = 44 - 24
5 x =20
x = 4
C) 8 x = - 40 + 32
8 x = - 8
x= - 1
d)x = - 5
e) -3x - 20 = - 35
- 3 x = - 35 + 20
- 3 x = - 15
x = 5
f) - 2 x = - 18 - 80
- 2 x = - 98
x = 49
