Question

Calcule o Valor de x: Lembrando que o ponto significa multiplicação
a)2.x + 1=7
b)5.x - 2=8
c)2.x + 1=15
d)6.x - 3=9
e)5.x - 2=23
f)3.x + 1=76
g)3.x - 2=16
h)4.x + 1=33
i)3,x - 7=65
j)5.x - 10 =80​

Answer 1

Resposta:

a) 2x = 7 - 1

2x = 6

x = 6

b) 5x = 8 + 2

5x = 10

x = 2

c) 2x = 15 - 1

2x = 14

x = 7

d) 6x = 9 + 3

6x = 12

x = 2

e) 5x = 23 + 2

5x = 25

x = 5

f) 3x = 76 + 1

3x = 75

x = 25

g) 3x = 16 + 2

3x = 18

x = 6

h) 4x = 33 - 1

4x = 32

x = 8

i) 3x = 65 + 7

3x = 72

x = 24

j) 5x = 80 + 10

5x = 90

x = 18
