Question

calcule x e y na proporcao x/y = 8/3, sabendo que x + y = 132

Answer 1

x/y = 8/3
3 x = 8 y
x = 8 y/3
x + y = 132
8 y /3 + y = 132
m.m.c = 3
8 y/3 + 3 y/3 = 396/3 eliminar o denominador
8 y + 3 y = 396
11 y = 396
y = 396/11
y = 36
x + y = 132
x + 36 = 132
x = 132 - 36
x = 96

96/36 = 8/3
