Question

Resolva a equação

a)18x - 14 =47
b)35x - 28 = 18x + 45
c158 + 27 x = -85 x + 13

Answer 1

a) 18x-14=47

18x=47+14

18x=61

B)35x-28=18x+45

35x(-28)=18+45

-980=18x+45

-18x-980=45

-18x=45+980

-18x=1025

18x= -1025

C)158+27x= -85x+13

158+27x +85x=13

27x +85x =13 - 158

112x=13 - 158

112x = - 145
