Question

a+b=1.10 a=b+1. What are the values of a and b?

Answer 1

Subtitute a = b + 1 to a + b = 1.1

b + 1 + b = 1.1
2b + 1 = 1.1    |subtract 1 from both sides
2b = 0.1    |divide both sides by 2
b = 0.05

Subtitute the value of b to a = b + 1

a = 0.05 + 1 = 1.05

Answer: a = 1.05 and b = 0.05
