Mathematics

diamong [38]3 years ago
3 0

Answer:

x = y - 6.4

Steps :

1. Create an equation

If x-4=0 and y-10.4=0, then x - 4 = y - 10.4

x - 4 = y - 10.4

2. Isolate variable X by adding 4 to both sides

x = y - 6.4

3. (Optional) Check Answer by plugging given values into the equation

(4) = (10.4) - 6.4

4 = 4 is a true statement
