one block in a small neighborhood has a total of 15 bycicles and trycicles. Altogether, there are 45 wheels. which system of equations can be used to find the number of bycicles and trycicles?

Step-by-step explanation:

b + t = 15, 2b + 3t = 45

If you need it solve:

2(b + t) = 2(15)

2b + 2t = 30  Now subtract this from the second equation

 2b + 3t = 45

- 2b + 2t = 30

t = 15

There are 15 trycicles and 0 bycicles

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
