Question

Resolva as equações , sendo U=Q

Answer 1

Resposta:

a) x = 0 + 3

x = 3

b) x = 7 - 15

x = -8

c) 2x  = -4

x = -4/2

x = -2

d) x = 9/3

x = 3

e) 6x - 3x = -5 -1

3x = -6

x = -6/3

x = -2

f)  3x + 2x = 60

5x = 60

x = 60/5

x = 12

g) (x -1)/2    =   (x+1)/3

3x -3 = 2x + 2

3x - 2x = 3 + 2

x = 5
