Question

What property is used to transform the equation 3x + 2y + 14 = 32 into 3x + 2y + x – 2y = 32?

Answer 1

The property used is called “Substitution Property”.

In here, x – 2y = 14

Substituting the left hand-side of this equation to the “14” in 3x + 2y + 14 = 32 would result in 3x + 2y + x – 2y = 32.
