Question

1 v+ 1 b= 103 yuan
1v+ 1 p= 83.5 yuan
P=
V=
B=

Answer 1

To solve this system of equations, we can use the substitution method.

From the first equation:
1v + 1b = 103
b = 103 - v

Substitute b = 103 - v into the second equation:
1v + 1(103-v) = 83.5
1v + 103 - v = 83.5
103 = 83.5
19v = 20.5
v = 20.5/19
v ≈ 1.079 yuan

Now substitute v back into b = 103 - v:
b = 103 - 1.079
b ≈ 101.921 yuan

Finally, substitute v and b back into the first equation to find p:
1.079 + 101.921 = p
p ≈ 83.5 yuan

So, the values are:
V ≈ 1.079 yuan
B ≈ 101.921 yuan
P ≈ 83.5 yuan
