Answer:b is the right choice hopefully dont be mad if it is wrong
Step-by-step explanation:
Write and solve an equation, as follows:
-7y + 5(3+ny) = 3y + 15. We are to find the value of 'n.'
-7y + 15 + 5ny = 3y + 15.
Subtracting 15 from both sides, we get -7y + 5ny = 3y
Grouping like terms, we get 5ny = 3y + 7y = 10y
Dividing both sides by 5y, we get n = 2 (answer)
Slope = change in y over change in x
= (5-3) / (4 - -2)
= 2/6 = 1/3
Answer:
Option C (None Of The Above)
Step-by-step explanation:
Given expression = 
Lets multiply the numerator and denominator by -1.


Now , lets open the brackets.

But as this expression is not there in the given options , the correct answer will be Option C.
3x+1/10=x-1/7
subtract 1/10 from both sides
3x=-1/7-1/10+x
subtract x from both sides
2x=-1/7-1/10
add -1/7 and -1/0
1/7=10/70
1/10=7/70
-10/70-7/70=-17/70
2x=-17/70
divide by 2 ro multiply by 1/2
x=-17/140
