Question

resolva as seguintes equacoes do 1 grau com uma incognita,dentro do conjunto universo Q (a)x-1=10,(B)y+10=6,(C)12X+5=12,(D)8x-6=6x(E)3t-1=11,(F)t=8-2t,(G)6x-11=5x-3,(H)6x+9=4x+9,(I)8y-5=-2y+1,(J)5x-5=8x+2

Answer 1

a) x-1=10
x=10+1
x=11
b)y+10=6
y=6-10
y=-4
c)12x+5=12
12x=12-5
12x=7
x=7/12
d)8x-6=6x
8x-6x=6
2x=6
x=6/2
x=3
e)3t-1=11
3t=11+1
3t=12
t=12/3
t=4
f)t=8-2t
t+2t=8
3t=8
t=8/3
g)6x-11=5x-3
6x-5x=-3+11
x=8
h)6x+9=4x+9
6x-4x=9-9
2x=0
x=0
i)8y-5=-2y+1
8y+2y=1+5
10y=6
y=6/10 (:2) =3/5
j)5x-5=8x+2
5x-8x=2+5
-3x=7 (.-1)
3x=-7
x=-7/3
