Question

2)Resolva as Equações: a) a+5= +9 b) x+7= +3 c) a-3= +4 d) y-1= -5 e) x-4= -3 f) z+8= -7 g) 2.c= +18 h) 3.c= -24 i) x/6= +6 j) y/5= -4

Answer 1

Resposta:

a) a + 5 = 9 → a = 4

b) x + 7 = 3 → x = -4

c) a - 3 = 4 → a = 7

d) y - 1 = -5 → y = -4

e) x - 4 = -3 → x = 1

f) z + 8 = -7 → z = -15

g) 2.c = 18 → c = 9

h) 3.c = -24 → c = -8

i) x/6 = 6 → x = 36

j) y/5= -4
