Question

Resolva as Equações:

a) 2 ( 3X - 5 ) = 14

b) 2X - 1 = 3
--------
5

Answer 1

$a) 2 ( 3x - 5 ) = 14\to \\\\ 6x-10=14\to \\\\ 6x=14+10\to \\\\ 6x=24\to \\\\ x= \frac{24}{6} \to \\\\ x=4$




$b) \frac{2x-1}{5} =3\to \\\\ 2x-1=15\to \\\\2x=15+1\to \\\\ 2x=16\to \\\\ x= \frac{16}{2} \to \\\\ x=8$

Answer 2

a) 2.(3x - 5) = 14

6x - 10 = 14
6x = 14 + 10
6x = 24
x =  24 
       6
x = 4

b)  2x - 1  = 3
        5
2x - 1 = 15 
    5        5

2x - 1 = 15
2x = 15 + 1
2x = 16
x =  16 
        2
x = 8

Bons estudos..espero ter ajudado..(;
