Answer:
a = 1.5
b = 1.75
Step-by-step explanation:
First, we need to solve and replace the result in the initial equation as:
Then, this equality apply only if the coefficient of is equal in both sides and the constant is equal in both sides.
It means that we have two equations:
So, using the first equation and solving for a, we get:
Finally, replacing the value of a in the second equation and solving for b, we get:
