Question

Resolva as equações abaixo:
a) x + 5 = 8
b) x - 7 = - 7
c) 2 x = 14
d) 4 x + 1=2 x - 7
e) 13 x - 2= 6 x + 9
f) 3 ( x - 2 ) =2 x - 4
g) x + 5 = 13
h) x – 11 = 25
I) 2.x + 4 = 24
j) 3.x – 8 = 22

Answer 1

a) x+5=8
x=8-5
x=3

b) x-7=-7
x=-7+7
x= 0


C) 2x=14
x=14/2 (dividido )
x=7

D)4x+1=2x-7
4x-2x=-7-1
2x=-8
x= -8/2
X= -4
