Question

BOA TAAAARDE :^
Se puderem me ajudaaar :D

a) $x + \frac{1}{2}= \frac{3}{2}$

b) $\frac{x}{7} = -2$

c) $-9x + 8 = -43$

Answer 1

a) x + 1/2 = 3/2

   x= 3/2 - 1/2

   x= 2/2

   x= 1

b) x/7 = -2

   x= -14

   

c) -9x + 8 = -43

   -9x = -43 - 8

   -9x = -51

     x = -51/9

     x = 5,6666...
