Final answer:
To determine the value of y, we solve the given system of equations. However, the value of y cannot be determined for the given system.
Step-by-step explanation:
To determine the value of y, we need to solve the given system of equations:
Equation 1: 1x + 20 = 23
Equation 2: 4 + 5y = ?
For Equation 1, subtracting 20 from both sides gives us:
1x = 3
So x = 3.
Substituting the value of x into Equation 2:
4 + 5y = ?
4 + 5y = ? can't be solved since it's an incomplete equation. So, we can't determine the value of y for the given system of equations.
