Answer:
x = 4
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-5*x+15-(35-10*x)=0
Pull out like factors :
5x - 20 = 5 • (x - 4)
_________________________________________
Solve : 5 = 0
This equation has no solution.
A a non-zero constant never equals zero.
_________________________________________
Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4
Rational Number are set of numbers that can be written as a/b where a and b are integers, but b is not equal to 0; an integer or a fraction; for example: 6 can be expressed as 6/1 and 0.5 can be expressed as 1/2.
Answer/Step-by-step explanation:
A. 
Using b = 2

Using b = 4

Using b = 6

Using b = 8

Using b = 10

Using b = 2

B. 
Using x = 3

Using x = 5

Using x = 7

Using x = 9

Using x = 11

Using x = 13

C. 
Using a = 2

Using a = 3

Using a = 4

Using a = 5

Using a = 6

Using a = 7

D. 
Using y = 2

Using y = 3

Using y = 5

Using y = 10

Using y = 8

Using y = 6
