Question

quanto e?
A) 6x = 2x + 16
B) 2x - 5 = x +1
C) 4x - 10 = 2x 2
D) 3x - 2 = 4x +9
OBS: preciso das contas completas

Answer 1

A) 6x - 2x = 16
4x = 16
x = $\frac{16}{4}$
x = 4

B) 2x - x = 1 + 5
x = 6

C) 4x - 2x = 2 + 10
2x = 12
x = 6 

D) 3x - 4x = 9 + 2
- x = 11 (+1)
x = 11

  

Answer 2

A -
 6x = 2x + 16
 6x  - 2x = 16
4x = 16 
x = 16 ÷ 4
x = 4

B - 
2x - 5 = x + 1
2x - x = 1 + 5
x = 6

C - 
4x - 10 = 2x + 2
4x - 2x = 10 + 2
2x = 12
x = 12  ÷ 2
x = 6

D -
3x - 2 = 4x + 9
3x - 4x = 9 + 2
x = 11
