Question

Determine o valor de x que satisfaz a sentença
A)5x-10=35
B)6x-15=4x-21
C)2x-12=16
D)4x-10=2x-10

Answer 1

A)5x-10=35
5x = 35 + 10
5x = 45
x = 45/5
x = 9





B)6x-15=4x-21
6x - 4x = - 21 + 15
2x = - 6
x = - 6/2
x = -3




C)2x-12=16
2x = 16 + 12
2x = 28
x = 28/2
x = 14




D)4x-10=2x-10
4x - 2x = - 10 + 10
2x = 0
x = 0/2
x = 0

Answer 2

Boa noite!!

a)
5x -10 = 35
5x = 35 +10
x = 45/5
x = 9

b)
6x -15 = 4x -21
6x -4x = -21 +15
2x = -6
x = -6/2
x = -3

c)
2x -12 = 16
2x = 16 +12
2x = 28
x = 28/2
x = 14

d)
4x -10 = 2x -10
4x -2x = -10 +10
2x = 0
x = 0/2
x = 0

Bons estudos!
