Question

How many solutions does the equation 5x + 3x − 4 = 10 + 8x have? (4 points)

a
No Solution

b
One

c
Two

d
Infinitely many

Answer 1

Explanation:

`5x + 3x - 4 = 10 + 8x \\ 8x - 4 = 10 + 8x \\ 8x - 8x = 10 + 4 \\ = 14`

Since x has been eliminated (8x-8x = 0), there are no solutions in this equation.
