Question

Resolva as equaçoes, sendo u=q
A) x+ 1 /2 = 3/2
B) -9x +8 = -43
C) x-3 (4x)=7x-(1-x

Socorro e para amanha c eu n entregar eu vou ficar de recuperação

Answer 1

A) x + 1/2 = 3/2
2x + 1 = 3
2x = 3 - 1
2x = 2
x = 2/2
x= 1
B) - 9x + 8 = - 43 ( - 1)
9x -8 = 43
9x = 43 +8
9x = 51
x = 51/9
C) x - 3 (4x )= 7x - ( 1 - x )
x - 12x = 7x - 1 + x
x - 12x - 7x. - x = 1
- 17x = 1 ( -1 )
17x = - 1
x = - 1/17
