Question

rezolvati ecuatiile a) x+12=21 b) x-3=11 c)x .4 =20 d) x:8=12 e) 27+x=103 f) 108-x=54

g) 2727 :x=27 h) 43 .x=473

Answer 1

a)x+12=21
x=21-12
x=9

b)x-3=11
x=11+3
x=14

c)x*4=20
x=20:4
x=5

d)x:8=12
x=12x8
x=96

e)27+x=103
x=103-27
x=76

f)108-x=54
x=108-54
x=54

g)2727:x=27
x=2727:27
x=101

h)43*x=473
x=473:43
x=11

Answer 2

a) x=21-12=> x=9
b) x=11+3=> x=14
c) x=20:4=> x=5
d) x=12•8=> x=96
e) x=103-27=> x=76
f) x=108-54=> x=54
g) x=2727:27=> x=101
h) x=473:43=> x=11
