Final answer:
Adding 4 to the value of the equation 4x - 10y equals 64 gives us the new value of 68 for the expression 4 + 4x - 10y.
Step-by-step explanation:
To find the value of 4 + 4x - 10y given that 4x - 10y = 64 is a true equation, we can simply add 4 to both sides of the given equation. Since we know 4x - 10y equals 64, we can substitute 64 in place of 4x - 10y, and then add 4.
The substitution will look like this:
- 4 + (4x - 10y) = 4 + 64
- 4 + 64 = 68
Therefore, the value of 4 + 4x - 10y is 68.
