Olá!!!
Resolução!!!
x/2 + x/3 = 30
x/2 + x/3 = 30/1
MMC ( 2, 3 ) = 6
6 ÷ 2 = 3 • x = 3x
6 ÷ 3 = 2 • x = 2x
6 ÷ 1 = 6 • 30 = 180
3x/6 + 2x/6 = 180/6
3x + 2x = 180
5x = 180
x = 180/5
x = 36
S = { 36 }
Espero ter ajudado!!

Bruce tinha certa quantia em dinheiro, foi ao shopping e gastou 1/3 num livro, depois 1/4 num CD, e ainda ficou com 50 reais. Quantos reais ele tinha?
