2-var Cramer - find y (medium)

3 visual steps / 2-var Cramer find y

1. Coefficient D

Read y window in place, divide.Db4-123818same rowsDy48218D = 14Dy = 56y = 4
D = 14.

D = 14.

2. Target Dy

Read y window in place, divide.Db4-123818same rowsDy48218D = 14Dy = 56y = 4
Dy = 56.

Dy = 56.

3. y ratio

Read y window in place, divide.Db4-123818same rowsDy48218D = 14Dy = 56y = 4
y = 4.

y = 4.
