Question

1) Resolva as equações: a) a+7= +10 b) x+3= +2 c) a-3= +2 d) y-1= -4 e) x-7= -2 f) z+9= -1 g) 6.x= +24 h) 8.c= -48 i) x/3= +6 j) y/9= -2

Answer 1

Resposta:

a) a + 7 = 10 → a = 3

b) x + 3 = 2 → x = -1

c) a - 3 = 2 → a = 5

d) y - 1 = -4 → y = -3

e) x - 7 = -2 →x = 5

f) z + 9 = -1 → z = -10

g) 6.x = 24 → x = 4

h) 8.c = -48 → c =- 6

i) x/3 = 6 → x = 18

j) y/9 = -2 → y = -18
