Answer:
b = 4y
y = 1/4 * b
Step-by-step explanation:
Number of Blue fish = 16
Number of yellow fish = 4
Let:
Blue fish = b
Yellow fish = y
b = 4y
b = 4(4)
b = 16
From ;
b =4y
y = b/4
y = 1/4 * b
Hence,
y = 1/4 * 16
y = 16/4
y = 4
Answer:
x=5, y=-5.6
Step-by-step explanation:
-8x-10y=24
6x+5y=2
-8x-10y=24
2(6x+5y=2)
-8x-10y=24
12x+10y=4
4x=20
x=5
6x+5y=2
6(5)+5y=2
5y=2-30
y=-28/5
y=-5.6
