Henry has a total of 34 blue and green stickers. 1/3 of the blue stickers and half of the green stickers are rectangular. How many blue stickers does he have if he has a total of 15 rectangular stickers?

1 answer

Blues --- x
greens --- 34-x

(1/3)x + (1/2)(34-x) = 15
multiply by 6, the LCD
2x + 3(34-x) = 90

solve for x
