Question

Resolva as seguintes equações a)x+5+5x=-1 b)4x=32 c)-10=-x-8 d)2x-5=x+1

Answer 1

a)
$x + 5 + 5x = - 1 \\ 6x = - 1 - 5 \\ x = - \frac{6}{6} \\ x = - 1$
b)
$4x = 32 \\ x = \frac{32}{4} \\ x = 8$
c)
$- 10 = - x - 8 \\ - 10 + 8 = - x \\ x = 2$
d)
$2x - 5 = x + 1 \\ 2x - x = 1 + 5 \\ x = 6$

Answer 2

a) x+5+5x=-1
6x(pois soma x+5x)
6x=-1-5
6x=-6
x=6/-6
x=-1

b) 4x=32
x=32/4
x=8

c) -10=-x-8
x=-8+10
x=2

d)2x-5=x+1
2x-x= +1+5
X=6
