Question

2). Resolva as equações a seguir:
a)14x - 40 = 35 b) 26x - 16 = 12 - 15x c) 12y - 3 (1 + y) = 5 (2y - 1) – 16

Answer 1

a)14x-40=35

14x=35+40

14x=75

x=75/14

b)26x-16=12-15x

26x+15x=12+16

41x=28

x=28/41

c)12y-3 (1+y)=5 (2y-1)-16

12y-3-3y=10y-5-16

12y-3y-10y=-5-16+3

-y= -8

-y= -8 (-1)

y=8
