Answer:
I don't think there are any solutions... (No solution)
Step-by-step explanation:
 =-7-8
=-7-8
Simplify
 =-15
=-15
To isolate x square both sides:
  =
=
-15 cannot be squared since it is negative. Therefore, there is no solution.

Answer:
Step-by-step explanation:
Change mixed fraction to improper fraction. Then reduce to lowest term if possible.
6 1/4 x 3 3/5 = 25/4 * 18/5    = 25* 18 /4*5
                     = 5 * 18 / 4    {giving by 5th table}
                     = 5* 9 /2        { giving by 2nd tables}
                    = 45/2
