Question

1) Resolva as Equações e tire a prova real.
a) 2x + 6 = x + 18
b) 5x - 3 = 2x + 9
c) 4x - 3 = 3x + 18
d) 2x + 3(x - 5) = 4x + 9
e) 2(x + 1) - 3(2x - 5) = 6x - 3​

Answer 1

Explicação passo-a-passo:

a)2x+6=x+18

2x-x=18-6

x=12

b)5x-3=2x+9

5x-2x=9+3

3x=12

x=12/3

x=4

c)4x-3=3x+18

4x-3x=18+3

x=21

d)2x+3 (x-5)=4x+9

2x+3x-15=4x+9

2x+3x-4x=9+15

x=24

e)2 (x+1)-3 (2x-5)=6x-3

2x+2-6x+15=6x-3

2x-6x-6x=-3-15

-10x=-18

x=-18/-10

x=-1.8

Answer 2

Resposta:

a) x = 12

b) x = 4

c) x = 21

d) x = 24

e) x = 2
