Answer:
a. one solution (x = -8)
Explanation:
You want to know how many solutions there are for the equation 2x -48 = 8x.
Solution
This is a 2-step linear equation.
Step 1: subtract 2x from both sides.
-48 = 6x
Step 2: divide by the coefficient of x.
-48/6 = -8 = x
There is one solution: x = -8.

Additional comment
When x terms are on both sides of the equal sign, there will be one solution if their coefficients are different.
If the coefficients are the same, the number of solutions may be 0 or infinite, depending on the constant value(s).
