We have to solve this equation:
![2 * ln e ^{ln(5x)}= 2 * ln 15/:2 \\ ln e ^{ln(5x)}=ln 15 \\ e ^{ln(5x)}=15 \\](https://tex.z-dn.net/?f=2%20%2A%20ln%20e%20%5E%7Bln%285x%29%7D%3D%202%20%2A%20ln%2015%2F%3A2%20%5C%5C%20ln%20e%20%5E%7Bln%285x%29%7D%3Dln%2015%20%5C%5C%20e%20%5E%7Bln%285x%29%7D%3D15%20%5C%5C%20%20%20)
5 x = 15
x = 15 : 5
Answer:
x = 3
Answer:

Step-by-step explanation:
He has been out of town 18 out of the 30 days. You can simplify this to 6/10.
You have to multiply every number!!
Example: 8 x 6 x 3 x 3 x 4
Answer:
77
Step-by-step explanation:
Answer: (-1,4)
Step-by-step explanation:
y=-2x+2 y=7x+11 <----- substitute this equation for y in the
equation y=-2x+2
7x+11=-2x+2 Add 2x to both sides
9x+11=2 Subtract 11 from both sides
9x=-9 Divide both sides by 9
x=-1
y=-2(-1)+2 Plug in x to one of the equations, I chose y=-2x+2
y=2+2 because it was the easiest, then solve
y=4
Solution is (-1,4)
