Question

despejar:

x/5+2x/a = 14

Answer 1

x/5+2x/a = 14

(ax+5(2x)) / 5a = 14

(ax+10x) / 5a = 14

x(a+10)=14 (5a)
x(a+10)= 70a
x= 70 a / (a+10)

saludos

Answer 2

x/5 + 2x/a =14
(ax+ 10x)/5a =14
ax + 10x =14 * 5a
ax + 10x = 70ase divide todo entre 10 y queda
ax/10 + x = 7a
ax+ x =7a*10
ax +x = 70a
x+x= 70a/a se eliminanlas a
ax=70
x=45
