Question

Drag and drop the appropriate property next to each step to justify the step.

Answer 1

The given equation is

$2x-9 =-16$

Here we have to solve for x.

First we need to get rid of 9, and for that, we add 9 to both sides. That is

$2x-9+9=-16+9 \\ 2x =-7$      (Addition property of equality)

Now we need to get rid of 2, and for that, we divide both sides by 2.That is

$x = \frac{-7}{2}$   (Division property of equality) .

Answer 2

2x-9 = -16

Adding 9 on both sides

2x-9+9=-16+9------------[Addition property of Equality]

2x=-7

Dividing by ,2 on both sides, that is using Divison property of Equality

 $x=\frac{-7}{2}$
