Question

resolva as equações
 
a)2x+3=25
b)6+2x=12
c)3x=18
d)x+4=9

me ajudem POR FAVOR

Answer 1

a) 2x + 3 = 25
2x = 25 - 3
2x = 22
x = 22/2
x = 11

b) 6 + 2x = 12
2x = 12 - 6
2x = 6
x = 6/2
x = 3

c) 3x = 18
x = 18/3
x = 6

d) x + 4 = 9
x = 9 - 4
x = 5

Answer 2

 a)2x+3=25 ==> 2x = 25-3 ==> 2x = 22 ==> x =11
b)6+2x=12 ==> 2x = 12-6 ==> 2x = 6 ==> x =3
c)3x=18 ==> 3x = 18 ==>  x =6
d)x+4=9 ==> 2x = 9-4 ==> 2x = 5 ==> x = 5/2
