Question

RESOLVA AS QUESTÕES COM PARENTÊS:
A) a) 7(x-5)=3(x+1)
B) 3(x- 2) - =4 (-x+3)
C) 2(x+1) - (x-1) =0
D) 5(x+1) -3 (x+2)=0

Answer 1

A) 7(x-5)=3(x+1)

7x- 35= 3x+ 3

7x- 3x= 3 +35

4x= 38

X= 38/4

B) 3(x- 2) =4 (-x+3)

3x- 6 = - 4x+ 12

3x+4x= 12+6

7x= 18

X= 18/7

C) 2(x+1) - (x-1) =0

2x+ 2 - x +1= 0

2x-x= 0-1-2

X= -3

D) 5(x+1) -3 (x+2)=0

5x+ 5 -3x - 6= 0

5x-3x= 0+6-5

2x= +1

X= 1/2

Espero ter ajudado ;)
