Explicação passo a passo:

Answer 2

Resposta:

A)

===================

$4x+2=38\\4x=38-2\\4x=36\\x=\frac{36}{4} = 9\\4.9=36\\36=36$

===================

B)

===================

$9x=6x+12\\9x-6x=12\\3x=12\\x=\frac{12}{3}=4\\3.4=12\\12=12$

===================

C)

===================

$5x-1=3x+11\\(5x-3x = 2x)\\2x-1=11\\2x = 11+1\\2x=10\\x=\frac{10}{2}=5\\2.5=10\\10=10$

===================

D)

===================

$2x+8=x+13\\2x=x+13-8\\2x=x+5\\(x=1x)\\1x=5\\x=\frac{5}{1} = 5\\1.5=5\\5=5$
