Olá Tudo Bom!!

g)

= 2x+8= 12
= 2x= 12-8
= 2x=4
= x= 2/4
= x= 2

S= { 2 }

h)

= 3x+2= 2x-11
= 3x-2x= -11-2
= x= -13

S= { -13 }

i)

= 5x-1= 2x+14
= 5x-2x= 14+1
= 3x= 15
= x= 15/3
= x= 5

S= { 5 }

j)

= 6x= 2x+16
= 6x-2x= 16
= 4x= 16
= x= 16/4
= x= 4

S= { 4 }

k)

= 2x-5= x+1
= 2x-x= 1+5
= x= 6

S= { 6 }

l)
= 4x-10= 2x+2
= 4x-2x= 2+10
= 2x= 12
= x= 12/2
= x= 6

S= { 6 }

Espero Ter Ajudado!!Bons Estudos!!❤
