Question

Resolva as equações

d) 5x - 1 = 8x + 5 e) x + 5 = 8 f) x - 4 = 3 g) x + 6 = 5

Answer 1

d)
5x - 1 = 8x + 5
5x-8x = 5+1
-3x = 6  (-1)
3x = -6
x = -6/3
x = -2
________________________________________
e)
x + 5 = 8
x = 8-5
x = 3
________________________________________
f)
x - 4 = 3
x = 3+4
x = 7
________________________________________
g)
x + 6 = 5
x = 5-6
x = -1

Forte abraço!

Answer 2

d) 5x -1 = 8x + 5 
5x - 8x = 5 + 1
3x = 6
x = 2

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

f) x -4 = 3
x = 3 +4
x = 7

g) x +6 = 5
x= 5 -6
x = -1
