Question

a)x+4=15 b)2x-5=x+10 c)5x-3x-8=29+9x d)5-(4x+2)=8+2(x-1) e)3x-10+13=-2x+28 f)13x-23-45=-7x+12

Answer 1

Resposta:

Explicação passo a passo:

A) x= 15 - 4

x= 11

B) 2x-x= 10+5

x= 15

C) 5x - 3x - 9x = 29+8

-7x= 37

x= - 37/7

D) -4x -2x= 8 - 2 - 5 + 2

- 6x = 3

x = - 1/2

E) 5x = 25

x = 5

F) 20x = 80

x= 4
