Question

3) Resolva as equações:
a) x + 5 = 18
b) x - 27 = 0
c) x + 25 = 36
d) y - 14 = 22
e) 4. y = 32
f) 5. y = 45
n 2-2
g) = = 7​

Answer 1

Explicação passo-a-passo:

a) x = 18 - 5 = 13

x = 13

b) x = 27

c) x = 36 - 25 = 11

x = 11

d) y = 22 + 14 = 36

y = 36

e) 4y =32

y = 32/4

y = 8

f)5y = 45

y = 45/5

y = 9

g) n = 7
