Resolvé las ecuaciones
a) x+7.3-13=504:2^2
b) (x+12) :8=216
c) 23+4x +15=5^3 +3^0
d) x:6-39 =375
e) (12+2x).8=2^7

Answer 1

a) x+7.3-13=504:2^2
x+ 21 - 13 = 504: 4
x + 21 - 13 = 126
x = 126-21+13
x = 118

b) (x+12) :8=216
(x+12) = 216.8
(x+12) = 1728
x= 1728-12
x= 1716

c) 23+4x +15=5^3 +3^0
23+4x+15 = 125+1
4x = 125+1-23-15
4x= 88
x= 88/4
x= 22

d) x:6-39 =375
x:6 = 375+39
x:6 = 414
x= 414.6
x= 2484

e) (12+2x).8=2^7
(12+2x) .8 = 128
(12+2x) = 128/8
(12+2x) = 16
2x = 16-12
2x= 4
x= 4/2
x= 2
