Question

How many solutions does the following equation have?

5x+8-7x=-4x+1

Answer 1

Answer:

One - it is x = -7/2

Step-by-step explanation:

We can solve the equation as follows:

5x +8 -7x = -4x +1

-2x  + 8  = -4x +1

    2x +8 = 1    

        2x = -7

          x = -7/2

So there is only one (i.e. a unique) solution for x.
