Question

25x = 125x + 3

x = −10
x = −9
x = −3
x = 3

Answer 1

Answer:

x=-9

Step-by-step explanation:

first you make the coefficients equal to each other by doing a common factor which in this case is 5. Then you have to do the variable for each time the common number is repeated which is 5^x * 5^x= 5^(x+3)*5^(x+3)*5^(x+3) This would make it equal to 5^2x=5^(3x+9). Since the non exponents are common factors you can get rid of them and solve for the exponent by doing 2x=3x+9. You solve that equation to get x=-9.

Answer 2

x = - 0.03

25x = 125x + 3

subtract 125x from both sides

25x - 125x = 125x - 125x + 3

-100x = 3

divide both sides by -100

x = 3 / -100

x = - 0.03
