A) 2x+26 = 30
2x = 30-26
x = 4/2
x = 2 

b) 8-2x+10 = 5
8+10-5 = 2x
13 = 2x
x = 13/2
x = 6,5

c) 3y-3-4y-8 = 6
-3-8-6 = -3y+4y
-17 = y

d) 10y+2 = 27
10y = 27-2
y = 25/10
y = 2,5

e) 2y-3y-3 = 8-2y-4
2y-3y+2y = 8-4+3
y = 7

f) 6x-5-5x = 10x+6
-5-6 = 10x-6x+5x
-11 = 9x
x = -11/9
x = -1,22

g) 6x+12 = 4x+24
6x-4x = 24-12
2x = 12
x = 12/2
x = 6

Não sei se está tudo correto, mas espero ter ajudado.

Bons Estudos!​
