a)8x+1=25
b)10x-5=95
c)13x=169
d)x+3>4
e)x-9>16
f)9x+16<25
g)18.x<36

Answer 1

encontre o valor de x:

a) 8x+1=25

8x = 25 - 1 = 24, x = 24/3 = 8

b) 10x-5=95

10x =95 + 5 = 100

x = 10

c) 13x=169

x = 169/13 = 13

d) x+3>4

x > 4 - 3

x > 1

e) x-9>16

x > 25

f) 9x+16<25

9x < 9

x < 1

g) 18x < 36

x < 2
