Answer 1

olá !!!

$a)\\10a-16=2a\\10a-2a=16\\8a=16\\a=\frac{16}{8}\\a=8$

$b)\\4x-6=x\\4x-x=6\\3x=6\\x=\frac{6}{3} \\x=3\\\\c)\\x=8-3x\\x+3x=8\\4x=8\\x=\frac{8}{4} \\x=4\\\\d)\\2x+3x+12=x\\5x-x=-12\\4x=-12\\x=\frac{-12}{4} \\x=-4\\\\e)\\4x-8=2x+12\\4x-2x=12+8\\2x=20\\x=\frac{20}{2} \\x=10\\\\f)\\5y-6=y+18\\5y-y=18+6\\4y=24\\y=\frac{24}{4} \\y=6$

espero ter ajudado
