Answer:
Step-by-step explanation:
Using the change of base rule for logarithms
x = ( where c is the new base )
Given
log 17 , that is 17 , then
17 =
-108=8x
Divide 8 on both sides
-13.5=x
The answer is...X=-13.5

Answer:
x = 9
Step-by-step explanation:
When doing these types of problems, the main goal is to get the variable by itself. Its kind of hard to explain with words so I will just use numbers.
15x + 14 = 149
(Subtract 14 on both sides. Remember, when you do something (Like subtracting, adding, etc.) on one side you have to do it to the other.)
15x + 14 = 149
-14 = -14
---------------------------
15x = 135
(Divide 15 on both sides. Since we need to use inverse operation to cancel the 15 out, we would divide 15 on both sides.)
15x/15 = 135/15
x = 9
Hope this helps :)
1. x/9+10=11 (x=89)
2. 3x-5=-2 (x=1)
3. 2x+15=-23 (x=19)
4. 5x-4=16 (x=4)
5. -8x+9=-7 (x=2)
6. 10x-12=-28 (x=1.6)
7. 3x+7=52 (x=15)
8. 5x-11=19 (x=6)
9. 4x+13=-91 (x=-26)
10. 2x-7=43 (x=-19)
The answer is 4.0120603015
