Question

como hacer este ejercicio no le entiendo paso a paso xfavor
a)6×+9=5×+15
b)9-2×=15-×
c)15-3×=26-4×
d)7×+5×-9+1=8×+5×-5
e)5×+6×-8+3=12×+3
f)4×+6-2×=×+10​

Answer 1

Respuesta:

a)6×+9=5×+15 =

= 6x - 5x = 15 - 9 =

= x = 6

b)9-2×=15-× =

= x - 2x = 15 - 9 =

= - 1x = 6 =

= x = 6/-1=

= x = - 6

c)15-3×=26-4× =

= 4x - 3x = 26 - 15 =

= x = 11

d)7×+5×-9+1=8×+5×-5 =

= 7x + 5x - 8x - 5x = 9 - 1 - 5 =

= -1x = 3 =

= x = 3/-1 =

= x = - 3

e)5×+6×-8+3=12×+3 =

= 5x + 6x - 12x = 3 - 3 + 8 =

= -1x = 8 =

= x = 8/-1 =

= x = - 8

f)4×+6-2×=×+10​ =

= 4x - 2x - x = 10 - 6 =

= x = 4
