Resposta:

) 9

B) 4

C) 6

D) 5

Explicação passo-a-passo:

A)

\begin{gathered}4x +2 = 38\\4x = 38 -2\\4x = 36\\x = 36/4\\x = 9\end{gathered}4x+2=384x=38−24x=36x=36/4x=9

B)

\begin{gathered}9x = 6x + 12\\9x - 6x = 12\\3x = 12\\x = 4\end{gathered}9x=6x+129x−6x=123x=12x=4

C)

\begin{gathered}5x - 1 = 3x + 11\\5x - 3x = 11 + 1\\2x = 12\\x = 6\end{gathered}5x−1=3x+115x−3x=11+12x=12x=6

D)

\begin{gathered}2x + 8 = x + 13\\2x - x = 13 - 8\\x = 5\end{gathered}2x+8=x+132x−x=13−8x=5
