3x + 4 = x+ 8   >  3x - x = 2x   >  2x + 4 = 8 >  8 - 4 = 4 > 2x / 2 crosses out > 4 / 2 = 2 > x=2
2y + 5 = y + 7 >  2y - y = y >  y+ 5 = 7 >  7-5= 2 > y=2

Answer: The linear system of equations that models this scenario are 
T + B = 15
3T + 2B = 38
Step-by-step explanation:
Let T represent the number of tricycles.
Let B represents the number of bicycles ordered.
The recreation center ordered a total of 15 tricycles and bicycles from a sporting good store. It is expressed as 
T + B = 15
A tricycle has three wheels. A bicycle has 2 wheels. The number of wheels for all tricycles and bicycles total 38. The expression would be 
3T + 2B = 38
