b) x = 23

c) x = 10

d) x = 6

e) x = $\frac{4}{3}$   ou   x = 1.33333333333

f) x = 2

Explicação passo a passo:

$a)\\5x+3x=16\\\\8x=16\\\\x=\frac{16}{8} \\\\x=2\\\\\\\\b)\\x+x+8=54\\\\2x+8=54\\\\2x=54-8\\\\2x=46\\\\x=\frac{46}{2} \\\\x=23\\\\\\\\c)\\7x-2-5x=18\\\\2x-2=18\\\\2x=18+2\\\\2x=20\\\\x=\frac{20}{2} \\\\x=10$

$d)\\12x-10x-4=8\\\\2x-4=8\\\\2x=8+4\\\\2x=12\\\\x=\frac{12}{2} \\\\x=6\\\\\\\\e)\\8x=5x+4\\\\8x-5x=4\\\\3x=4\\\\x=\frac{4}{3} \\\\x=1.33333333333\\\\\\\\f)\\10x-12=4x\\\\10x-4x=12\\\\6x=12\\\\x=\frac{12}{6} \\\\x=2$
