Let X be the number of bicycles
Let y be the number of unicycles
The equation for the number of tires is: 2X + Y = 46
Since there are 8 more bicycles than unicycles, we also have X = Y + 8
Substitute Y + 8 for X in the first equation to get:
2(Y + 8) + Y = 46
Solving for Y: 2Y + 16 + Y = 46; 3Y = 46 - 16; 3Y = 30; Y = 10
X = Y + 8 = 10 + 8 = 18
18 bicycles and 10 unicycles
