Answer 1

Resposta:

a)26x-39-10+5x=-15+30x

26x+5x-30x=-15+10+39

31x-30x=-5+39

x=34

b)4x+14+9x-15=12x+15-1

4x+9x-12x=15-1-14+15

13x-12x=14-14+15

x=0+15

x=15

c)3-7+14x=5-x-9

14x+x=5-9-3+7

15x=-4-3+7

15x=-7+7

15x=0

x=0/15

x=0

d)1+3x-1+2x-11-7x=5

3x+2x-7x=5-1+1+11

5x-7x=4+1+11

-2x=5+11

-2x=16 (-1)

2x=-16

x=-16/2

x=-8

e)2-10y-3-3y+28-8y=-y

-10y-3y-8y+y=-28+3-2

-13y-8y+y=-25-2

-21y+y=-27

-20y=-27 (-1)

20y=27

y=27/20

f)x-12+3x=7x-1+x

x+3x-7x-x=-1+12

4x-7x-x=11

-3x-x=11

-4x=11 (-1)

4X=-11

X=-11/4
