Answer:
The correct option is b.
Step-by-step explanation:
To find the number of solutions, we need to solve the equation:
[tex] 5x + 3(x - 1) = 10x - x - 5 [/tex]
Let's group all the "x" on the equation.
[tex] 5x + 3x - 10x + x = 3 - 5 [/tex]
Now, let's solve for "x".
[tex] -x = -2 [/tex]
[tex] x = 2 [/tex]
Therefore, the equation has one solution. The correct option is b.
I hope it helps you!
