Question

resolva as equações.

f)6(3x+2)-8= -2

g)-3(x-5)-2(2x+1)= -8


pelo amor de deusssss ajude mim ...........l...............

Answer 1

18x +12 -8=-2
18x+12-8+2=0
18x+6=0
a=18 b=6 c=0

Answer 2

Letra f)

6(3x+2) - 8 = -2
18x + 12 - 8 = -2
18x + 4 = -2
18x = -2 -4
18x = -6
x = -6/18 ou x = -1/3

x = 0,333...


Letra g)

-3(x-5)-2(2x+1)= -8
-3x + 15 - 4x - 2 = -8
-7x + 13 = -8
-7x = -8 - 13
-7x = -21 (-1)
x = 21/7
x = 3
