Question

Resolva:
2x+1=9
7x-3=3x+13
100x=300
2x=26

Answer 1

Olá,




2x+1= 9                                 
2x= 9-1
2x= 8
x= 8/2
$\boxed{x=4}$
__________________________________________________________


7x -3 = 3x + 13
7x - 3x = 13 + 3
4x = 16
x = 8/2
$\boxed{x=4}$
__________________________________________________________


100x = 300
x = 300/100
$\boxed{x=3}$
__________________________________________________________


2x = 26
x = 26/2
$\boxed{x=13}$
__________________________________________________________
