Question

3(x + 1) +2 (2x -3) = 5 (x - 1) + 8

Answer 1

Boa Tarde !!!

$3(x + 1) +2 (2x -3) = 5 (x - 1) + 8\\\\ \longrightarrow Multiplicamos\ o\ n\'umero\ de\ fora\ dos\ parenteses\ pelos\ de\ dentro.\\\\ \longrightarrow Separamos\ o\ que\ tiver\ x\ de\ um\ lado\ e\ o\ que\ n\~{a}o\ tiver\ de\ outro.\\\\3x + 3 + 4x - 6 = 5x - 5 + 8\\\\3x + 4x - 5x = 8 + 6 - 3\\\\2x = 11\\\\x = \frac{11}{2} \\\\x = 5,5$

Espero ter ajudado :-)

Resposta ↓

              x = 3

Explicação passo-a-passo:

3(x + 1) + 2 (2x - 3) = 5 (x - 1) + 8

3x + 3 + 4x - 6 = 5x - 5 + 8

7x - 3 = 5x + 3

7x - 5x = 3 + 3

2x = 6

x = 6 / 2

x = 3
