Question

Rezolvati in R urmatoarele ecuatii :
1. 6(x-2)=4
2. 4(x+9)=6


PLS AJUTOR!!!!

Answer 1

 1.
6(x-2)=4 
6x - 12 = 4
6x = 4 + 12
6x = 16
x = 16 :6
x = 2,(6) 

2.
4(x+9)=6
4x + 36 = 6
4x = 6 - 36
4x = - 30 
x = - 30 : 4
x = - 7,5  

Answer 2

 1. 
6(x-2)=4   :2
3(x -2) = 2
3x-6=2
3x=8
x=8:3
x = 2,(6) 

2. 
4(x+9)=6     :2
2(x + 9) = 3
x+9=3:2
x=1,5-9
x=-7,5
