Question

Solutia ecuatiei 2x=(3+1)²
Solutia ecuatiei 3(x+2)=27
Solutia ecuatiei 2x+3=3x+2

Answer 1

2x=9+6+1
2x=16
x=16:2 x=8

3(x+2)=27
3x+6=27
3x=27-6
x=21:3  x=7

2x+3=3x+2
3-2=3x-2x
1=x  x=1

Answer 2

2x=(3+1)^2
2x=4^2
2x=16
x=16:2
x=8

3(x+2)=27
3x+6=27
3x=27-6
x=21:3
x=7

2x+3=3x+2
2x-3x=2-3
-x=-1
x=1
