Mathematics

Margarita [4]3 years ago
7 0

Step-by-step explanation:

x log(5)  -  log(125)  = 0 \\  log( {5}^{x} )  -  log(125)  = 0 \\  log( \frac{5x}{125} )  = 0 \\  \frac{ {5}^{x} }{125}  = 1 \\  {5}^{x}  = 125 \\

log( {5}^{x} )  =  log(125)  \\ x log(5)  =  log(125)  \\ x =  \frac{ log(125) }{ log(5) }  = 3

3x = -x - 4
Add x to both sides
4x = -4, x = -1
Y = 3(-1), y = -3
Solution: x = -1, y = -3
