Question

Associe a 2- coluna com a 1- coluna

a)3x-1=8 ( )-3/4
b)3x-1=5x ( )4
c)x+7x-2x=96+2x ( )24
d)x+6=0,5x ( )-12
e)8x-7=-2x+5 ( )-1/2
f)4x-12=x ( )3
g)7x+23-x=2x+20 ( )1/5

Answer 1

a) 3x = 9
x = 9/3
x = 3

b) 3x - 5x = 1
-2x = 1
x = -1/2

c) 4x = 96
x = 96/4
x = 24

d) x - 0,5x = -6
1/2x = -6
x = -6/ 1/2
x = -12

e) essa acho q ta escrito errada
10x = 12
x = 12/10
x = 6/5

f) 3x = 12
x = 12/3
x= 4

g) 6x -2x = 20 - 23
4x = -3
x = -3/4
