Question

a) x+2x-1-3=x

b)-3x+10=2x+8+1

c)5x-5+x=9+x

d)7x-4-x=-7x+8-3x
​

Answer 1

Explicação passo-a-passo:

a) 3x - 4 = x

3x - x = 4

2x = 4

x = 4/2

x = 2

b) -3x - 2x = 9 -10

-5x = - 1

x = -1/-5

x = 1/5

c) 6x -5 = 9 + x

6x - x = 9 +5

5x = 14

x = 14/5

d) 6x - 4 = -10x + 8

6x + 10x = 8 +4

16x = 12

x = 12/16

x = 6/8
