Question

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

Olá!!!


Resolução!!!


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 = 15

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
