Question

. Rezolvaţi ecuaţiile: a. 3x=6; b. 5+x=8; c. 2x+10=x+20;
pls am nevoie la c
e urgent

Answer 1

a) 3x = 6

x = 6 : 3 = 2

b) 5 + x = 8

x = 8 - 5 = 3

c) 2x + 10 = x + 20

2x - x = 20 - 10

x = 10

Answer 2

Salut!

$a)3x = 6 \\ = > 6 \div 3 = 2$

$b)5 + x = 8 \\ x = 8 - 5 \\ x = 3$

$c)2x + 10 = x + 20 \\ 2x - x = 20 - 10 \\ x = 10$
