Answer:
A logarithm is the power to which a number must be raised in order to get some other number.
Step-by-step explanation:
For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.
9x+ 5y=35
2x + 5y=0 |* -1
9x +5y= 35
-2x -5y= 0
-----------------
7x / = 35
x=35:7
x=5
2x+5y=0
2*5+5y=0
10+5y=0
5y=-10
y= -10:5
y=-2
