Answer:

No solutions

Explanation:

Pre-Solving

We are given the following equation:

6x + 4x - 1 = 2(5x + 4)

We want to figure out how many solutions this has: one solution, infinetly many, or no solutions.

We can solve the equation in order to figure this.

Solving

First, combine 4x and 6x together.

10x - 1 = 2(5x + 4)

Now, distribute 2 to both 5x and 2.

10x - 1 = 10x + 8

Subtract 10x from both sides

-1 = 8

This is a false statement. No matter what value of x we put in, it will end up in a false statement.

This means this equation has no solutions.
