2) Determine a raiz de cada equação a seguir (resolva descobrindo o valor do termo x desconhecido), considerando U = Q:
a) x - 17 = -9
g) 3. (x+2) + 5 = x + 12
b) 2x = -7
h) x + 4.(x - 1) = 9 -2.(x + 3)
c) 3x + 2 = 2x - 11
i) 5.(3x - 2) = 2.(6x + 3)
d) 2x = 16
i) 2.(3x-1) +2.(3-X)= 0
e) x = -5
2
k) 7.(x-1) = 2.(3x+1)
f) 2x + 14 = 5x - 1
1) 2.(3 - y) +7.(2 - y) = 15 - 4y​

Find the values of y: 3y^3(y^2+ 2/3y)=0
