Resolva as equações:

a)2x + 2 = 13
b)3x + 250 = 700
c) 3x + 12 = 24
d) 8x - 24 + 10 - 2x = -x
e) 6 - 6x = - 7x​

Answer 1

Resposta:

a)11/2

b)150

c)4

d)2

e)-6

a)2x+2=13

2x=13-2

2x=11

x=11/2

b)3x+250=700

3x=700-250

3x=450

x=150

c)3x+12=24

3x=24-12

3x=12

x=4

d)8x-24+10-2x= -x

6x-14= -x

6x+x=14

7x=14

x=2

e)6-6x=-7x

-6x+7x=-6

x= -6

Bons estudos!!!
