Answer 1

a)4x=33-1
4x=32
x=32÷4
x=8
b)x-109=5
x=5+109
x=114
c)4=x-10
-x=-10-4
-x=-14
x=+14
d)3x-2x=3x+2
3x-2x-3x=+2
-2x=+2
x=2÷2=1
e)x+9=-1
x=-1-9
x=-10
f)2-3x=-2x+12-3x
-3x+2x+3x=+12-2
+2x=+10
x=10÷2
x=5
g)não existe por isso não vou fazer ksksks
h)x-4=3
x=3+4
x=7
i)x+5=8
x=8-5
x=3
j)9x+3=8x
9x-8x=+3
x=+3
k)x+28=11
x=11-28
x=-17
l)7=x+8
7-8=x
-1=x
m)-x-5+4x=-7+6x+15
-x+4x-6x=-7+15+5
-3x=+13
x=13÷3
x=4,3333...Infinito
n)4x-4-5x=6+90
4x-5x=6+90+4
x=100
o)x+2x+3-5x=4x-9
x+2x-5x-4x=-9-3
-6x=-12
x=12÷6
x=+2

Espero ter ajudado!
