Question

3 (x - 1) +2 (2x + 3) = (x - 1) +10

A) 2
B) 3
C) 1
D) 4​

Answer 1

Resposta:

3 (x - 1) +2 (2x + 3) = (x - 1) +10

3x-3+4x+6=(x-1)+10

3x-3+4x+6=x-1+10

3x+4x-3+6=x+9

7x+3=x+9

7x-x=9-3

6x=6

x=6/6

x = 1

Resposta C

Answer 2

Resposta:

C) 1

Explicação passo a passo:

3 (x -1) +2 (2x +3) = (x -1) +10

3 +2 (2x +3) = (x -1) +10

3 +2 +5x = (x -1) +10

3 +2 +5x = +10

5x = 10 -3 -2

5x = 5

 x = 5

       5

 x = 1
