Without an equality sign the given terms can't be considered as equations but if you mean -2x = 10 and -5x = 25 then they are both equivalent inasmuch that the value of x in both equations works out as -5

No, they are not equivalent. 2x10 = 20 and 5x25 = 125.
-125
1X125 or 5X25 or any number of fractions but I won't go into those.
375To find the Least Common Denominator (LCD) of 15 and 125 you could make a list of their multiples until you find a number common to both lists:15: 15, 30, 45, 60, 75, 90, 105, 120, 135, ....125: 125, 250, ...This method can sometimes be tedious. A more 'scientific method is to find the prime factorization of each number|15 = 3x5125 = 5x25 = 5x5x5The LCD has to have enough factors in it to make each of the numbers. There has to be 1 three and 3 fives.LCD = 3x5x5x5 = 3x125 = 375.
