Question

determine o valor do x​

Answer 1

a) x = 3+5
x = 8

b) 2x = 16-10
2x = 6
x = 6/2
x = 3

c) 3x = 27 + 27
3x = 54
x = 54/3
x = 18

d) 2x = -25 + 39
2x = 14
x = 14/2
x = 7

e) 5x = -30 + 30
5x = 0
x = 0/5
x = 0

f) x = 72 - 105
x = -33

Answer 2

A) x= 3+5
x= 8

b) 2x+ 10= 16
2x= 16-10
2x= 6
X= 6/2
X= 3

c)3x-27= 27
3x= 27 + 27
3x= 54
X= 3/54
x=18

d) -39 + 2x= -25
2x= - 25 + 39
2x= 14
X= 14/2
X= 7

e) -30 + 5x=-30
5x= -30 + 30
5x= ∅

f) 105+ x= 72
X= 72-105
x= -33
