Answer 1

Resposta:

Explicação passo a passo:

a) 4(x+1)=12

4x+4=12

4x=12-4

4x=8

x=8/2

x=4

b) 5(3-x) -4x= 18

15-5x-4x=18

15-9x=18

15-18=9x

-3=9x

x= -3/9

d)25(x-2)-5x=16

25x-50-5x=16

20x=16+50

20x=66

x=66/20

x=3,3

e) 5x+8=2(x+7)

5x+8=2x+14

5x-2x=14-8

3x=6

x=2

f)6(3x+2)-8=-2

18x+12-8=-2

18x=-2-4

18x=-6

x=-6/18

x=-1/3

g)3(x+4)=2(x-8)

3x+1×=2x-16

3x-2x=-16-1

x=-17
