Question

Resuelve las siguientes ecuaciones:
a. 5x = -5
b. -2x = -6
c. 6x = 0
d. x + 8 = – 3
e. -x – 4 = 1
f. x – 2 = – 1
g. 2x – 3 = 3
h. 4x – 5 = 2

Answer 1

Explicación paso a paso:

a)

$5x = - 5 \\ x = - 5 \div 5 \\ x = - 1$

b)

$- 2x = - 6 \\ x = - 6 \div ( - 2) \\ x = 3$

c)

$6x = 0 \\ x = 0 \div 6 \\ x = 0$

d)

$x + 8 = - 3 \\ x = - 3 - 8 \\ x = - 11$

e)

$- x - 4 = 1 \\ - x = 1 + 4 \\ - x = 5 \\ x = 5 \times ( - 1) \\ x = - 5$

f)

$x - 2 = - 1 \\ x = - 1 + 2 \\ x = 1$

g)

$2x - 3 = 3 \\ 2x = 3 + 3 \\ 2x = 6 \\ x = 6 \div 2 \\ x = 3$

h)

$4x - 5 = 2 \\ 4x = 2 + 5 \\ 4x = 7 \\ x = 7 \div 4 \\ x = \frac{7}{4}$
