Question

2×3(3x+1)-143 ala e 3x nu ie ori si punctul ala e ori​

Answer 1

2 × 3 ( 3 x + 1 ) - 1 = 43

6 ( 3 x + 1 ) - 1 = 43

6 ( 3 x + 1 ) = 43 + 1

6 ( 3 x + 1 ) = 44

3 x + 1 = 44 : 6

3 x + 1 = 7, ( 3 )

3 x = 7, ( 3 ) - 1

3 x = 6, ( 3 )

x = 6, ( 3 ) : 3

x = 2, ( 1 )

Answer 2

Răspuns:

2*3(3x + 1) - 1 = 43

6*(3x + 1) = 44

18x + 6 = 44

18x = 38

x = 38/18 = 19/9
