a) X = 2 -1





b) 2x = x -3





c) 4x + x = 10 -5





d) 2x – 2= -2x +6





e) 4x – 7 = 2x – 8





f) 6m – 4 = 12 – 9m





​

Answer 1

Resposta:

a)

x=1

b)2x=x-3

2x-x=-3

x=-3

c)4x + x = 10 -5

5x=5

x=5/5

x=1

e) 4x – 7 = 2x – 8

4x-2x=-8+7

2x=-1

x=-1/2

f) 6m – 4 = 12 – 9m

6m+9m=12+4

15m=16

m=16/15
