Question

Rápido alguém pra me ajudar?

Answer 1

a) -2x+18=6x

-2x-6x = -18

-8x = -18

-x = -18/8

-x = -9/4 *(-1)

x= 9/4

b) 4x-30=11x

4x-11x=+30

-6x=30

-x= 30/6

-x=5 *(-1)

x=-5

c)2x+10=3x

2x-3x=-10

-x= -10 *(-1)

x=10

Answer 2

Resposta:

A) -2x + 18 = 6x  

6x + 2x = 18  

8x = 18  

X = 18 ÷ 8  

X = 2,25  

B) 4x – 30 = 11x  

11x – 4x = 30  

7x = 30  

X = 30 ÷ 7  

X = 4,28...  

C) 2x + 10 = 3x  

3x – 2x = 10  

x = 10
