Resolva as Equaçoes

a)3x=27
b)2x=-7
c)-8x=7
d)-15x=102
e)3x-1=32
f)4x-3=5
g)1-3x=14
h)7-5x=-3
i)4x-3=9x+7
j)1-10x=3x+5
k)2(x-3)-5(2-x)=0
l)x-5-3(1-x)=0

Answer 1

a) x = 27/3 = 9
b) x = -7/2 = -3,5
c)-8x = 7
8x = -7
x = -7/8
d)-15x = 102
15x = -102
x = -102/15 = -34/5 = -6,8
e) 3x -1 = 32
3x = 33
x = 11
f)4x -3 = 5
4x = 8
x = 2
g) 1-3x = 14
-3x = 13
3x = -13
x = -13/3
h) 7-5x = -3
-5x = -10
x = 10/5 = 2
i)4x-3= 9x + 7
-3 -7 = 9x-4x
-10= 5x
x = -2
j)1-10x = 3x +5
-7x = 4
x = -4/7
k)2x -6 -10 +5x = 0
7x = 16
x = 16/7
l) x-5-3+3x=0
4x -8 = 0
4x = 8
x = 2

É isso, deu muito trabalho kkkkk.
