Pfffffffffffffff

Answer 1

Explicação passo-a-passo:

a) 6x=2x+16

6x-2x=16

4x=16

x=16/4

x=4

b)2x-5=x+2

2x-x=5+2

x=7

c)2x+3=x+6

2x-x=6-3

x=3

d)5x+7=3x+11

5x-3x=11-7

2x=4

x=4/2

x=2

e)15x-2x=x+24

13x-x=24

12x=24

x=24/12

x=2

f)2x-4=16-2x

2x+2x=16+4

4x=20

x=20/4

x=5

g)5x+10=10x-35

-10x+5x=-10-35

-5x=-45

x= -45/5

x= -9
