# 1

The equations 9x-3=15 and 5x + 4=14 are equivalent if they have the same solution.

So let's solve 9x-3=15

Start with the given equation.

Add to both sides.

Combine like terms on the right side.

Divide both sides by to isolate .

Reduce.

So the solution of is

=======================================

Now let's solve

Start with the given equation.

Subtract from both sides.

Combine like terms on the right side.

Divide both sides by to isolate .

Reduce.

So the solution to is

Since the two equations have the same solution, this means that they are both equivalent.
