Question

How many solutions can be found for the equation 5x + 3(x − 1) = 10x − x − 5? (4 points)

Answer 1

Answer:

The correct option is b.

Step-by-step explanation:

To find the number of solutions, we need to solve the equation:

$5x + 3(x - 1) = 10x - x - 5$

Let's group all the "x" on the equation.  

$5x + 3x - 10x + x = 3 - 5$              

Now, let's solve for "x".

$-x = -2$                

$x = 2$    

Therefore, the equation has one solution. The correct option is b.

I hope it helps you!
