Question

01) Calcule o Valor de x:
a)x+5=-3
b)x+9= 4
c)-3+x= -8
d) -3= x+1
e)2x+10=-2
f)3x+3=12

Answer 1

Resposta:

a)x+5= -3

x = -3 - 5

x = - 8

b)x+9=4

x = 4 - 9

x = - 5

c)-3+x= -8

x = - 8 + 3

x = - 5

d)-3=x+1

x + 1 + 3 = 0

x = - 1 - 3

x = - 4

e)2x+10= -2

2x + 10 + 2 = 0

2x + 12 = 0

2x = - 12

x = -12/ 2

x = - 6

f)3x+3=12

3x + 3 - 12 = 0

3x - 9 = 0

3x = 9

x = 9/3

x = 3
