Question

Mim ajudem preciso dessas respostas para ontem.

A)10-2x=3x

B)x-3=6+4x

C)(7x-8)•2=6•(3x-4)

D)16x-6-7x=15+2x

Answer 1

A: 10 - 2x = 3x

10 = 5x

x = 10/5

x=2

B: x - 3 = 6+ 4x

-3x = 9 (-1)

3x = 9

x=9/3

x = 3

C: (7x - 8) . 2 = 6. (3x -4)

14x - 16 = 18x - 24

- 4x = 8 (-1)

x = 8/4

x = 2

D: 16x - 6 - 7x = 15 + 2x

9x -6 = 15 +2x

7x = 21

x = 21/7

x = 3
