Question

a)7×-1=13





b)6×=2×+28




c)6×-10=2×+14




d)3 (2×-1)=2(×+1)+3




e)3×(×-1-(2×-4)-1

f)×/2-×/4=1/2

​

Answer 1

Resposta:

a) 7x= 13+1

x=14/7

x=2

b)6x -2x=28

4x =28

x=28/4

x= 7

c) 6x -2x= 14 +10

4x= 24

x= 24/4

x=6

d) distributiva

6x -3=2x +2 +3

6x -2x = 2 + 3 + 3

4x = 8

x= 8/4

x=2
