Question 1157358
Pedro's age = p
Juan's age = 3p/4
<pr>
3p/4 + 6 = 4(p + 6)/5
<pr>
3p/4 + 6 = (4p + 24)/5
<pr>
5(3p/4 + 6) = 4p + 24
<pr>
15p/4 + 30 = 4p + 24
<pr>
4(15p/4 + 30) = 4(4p + 24)
<pr>
15p + 120 = 16p + 96
<pr>
-p = -24
<pr>
p = 24
<pr>
Pedro's age = p = <b>24</b>
Juan's age = 3p/4 = 3(24)/4 = 72/4 = <b>18</b>
