Answer 1

Explicação passo-a-passo:

A)18×-43=65

18x = 65 + 43

18x = 108

x = 108/18

x = 6

B) 23×-16=14-17×

23x+17x = 14+16

40x = 30

x = 30/40

x = 0,75

C) 10×-9=21+2×+3×

10x-2x-3x = 21 + 9

5x = 30

x = 30/5

x= 6

D) 3×-2×+10=10+5×-40

x-5x = 10-40-10

-4x = -40

x = -40/-4

x = 10

E) 3×-4=2×+8

3x-2x = 8 + 4

x = 12

F) 7×-2+4=10+5×

7x-5x = 10 +2 - 4

2x = 8

x = 8/2

x = 4

G) 19×-6+2=6×-4+10

19x-6x = 6 + 6 -2

13x = 10

x = 10/13

x = 0,7692

H) 10-×+2=3+×-1

-x - x = 3 - 1 - 10 - 2

-2x = -10

x = -10/-2

x = 5
