URGENTE!

Como se resolve essas equações?

Preciso da ajuda de vocêsT_T


4x-3-x+8=11


3x-3=x+5


16x-6-7x=15+2x




4.(X+1)=5+3.(2-x)


16x+2.(7x+8)-9=67


6.(4x+2)+7.(-5x+3)=66


3.(5+3x)+5.(x-1)=24

Answer 1

Resposta:

$a)4x-3-x+8=11\\4x-x=11-8+3\\3x=6\\x=6/3\\x=2$

$b)3x-3=x+5\\3x-x=5+3\\2x=8\\x=8/2\\x=4$

$c)16x-6-7x=15+2x\\16x-7x-2x=15+6\\7x=21\\x=21/7\\x=3$

$d)4.(x+1)=5+3.(2-x)\\4x+3x=5+3-1\\7x=7\\x=7/7\\x=1$

$e)16x+2.(7x+8)-9=67\\16x+14x+16-9=67\\30x=67-7\\30x=60\\x=60/30\\x=2$

$f)6.(4x+2)+7.(-5x+3)=66\\24x+12-35x+21=66\\-11x+33=66\\-11x=66-33\\x=33/-11\\x=-3$

$g)3.(5+3x)+5.(x-1)=24\\15x+9x+5x-5=24\\10+14x=24\\14x=24-10\\14x=14\\x=14/14\\x=1$
