Question

Algm me ajuda porfavor!! é urgente.

1) Resolva as equações:
a) x – 2 = 10 b) x – 5 = 15 c) x – 3 = 2 d) x + 4 = 8

e) x + 3 = 1 f) x + 8 = 10 g) x + 3 = 10 h) x – 3 = –1

i) 5x = 30 j) –6x = –12 k) 2x = – 8 l) 3y = 18

m) 2x = 0 n) –3x = 6

Answer 1

a)x-2=10

x=10+2

x=12

b)x-5=15

x=15+5

x=20

c)x-3=2

x=2+3

x=5

d)x+4=8

x=8-4

x=4

e)x+3=1

x=1-3

x=-2

f)x+8=10

x=10-8

x=2

g)x+3=10

x=10-3

x=7

h)x-3=-1

x=-1+3

x=2

i)5x=30

x=30/5

x=6

j)-6x=-12

x=-12/-6

x=2

k)2x=-8

x=-8/2

x=-4

l)3y=18

y=18/3

y=6

m)2x=0

x=0/2

x=0

n)-3x=6

x=6/-3

x=-2
