Hope this helps!
∛(2x + 5) - 3 = 0
Add 3 to both sides
∛(2x + 5) = 3
Cube both sides
2x + 5 = 27
Subtract 5 from both sides
2x = 22
Divide both sides by 2
x=11
There's your answer. Have an awesome day! :)

Step-by-step explanation:
Descomponemos cada número en factores primos.
Después, señalamos los factores comunes.
A continuación, en cada uno de los comunes, escogemos el factor con menor exponente.
Y por ultimo, multiplicamos los factores elegidos.
195 3 275 5 315 3 460 2 525 3
65 5 55 5 105 3 230 2 175 5
13 13 11 11 35 5 115 5 35 5
1 1 7 7 23 23 7 7
1 1 1
Let x represent the amount Betty invested at 15%. The (2x+237) is the amount Betty has invested at 13%. Her total earnings are ...
x*0.15 + (2x+237)*0.13 = 1688.03
0.41x + 30.81 = 1688.03
x = (1688.03 -30.81)/0.41 = 4042.00
Betty has $4042.00 invested at 15%.
Betty has $237 +2*4042 = $8321.00 invested at 13%.
