Question

1)encontre o valor de x nas seguintes equações: a)x-14=-10
b)2x-6=12
c)2 (3-x)=-4x+8
d)3x-6=x+12
e)3-2x=-3x+10
f)3x-16=2 (x+10)​

Answer 1

Resposta:

a)x=-10+14

x=4

b)2x=16+6

2x=22

x=22/2

x=11

c)6-2x=-4x+8

4x-2x=8-6

2x=2

x=2/2

x=1

d)3x-x=12+6

2x=18

x=18/2

x=9

e)2x+3x=10-3

5x=7

x=7/2

f)3x-16=2x+20

3x-2x=20+16

x=36
