Question

3) Resolva as equações:
b) -2(x-2) = 3(x-1)
a) 2x -0,5 = 4x + 5,5
d) 8- (3-- 1) = 4 + ( 3x - 1)​

Answer 1

Resposta:

b) -2X-4=3X-3

-2X-3X=4-3

-5x=1

5X=-1

X= -1

5

a) 2X-4X=0,5+5,55

-2X= 1,05

-X= 1,05

2

X= -0,53

d) 24-8=12X+4

-12X=-8-24+4

-12X= -16+4

-12X= -12

X= 12

12

X= 1
