2( n+7)-7=9

multiply the bracket by 2

(2)(n)=2n

(2)(7)=14

2n+14-7=9

2n+7=9

move +7 to the other side

sign changes from +7 to -7

2n+7-7=9-7

2n=9-7

2n=2

divide both sides by 2 to get n by itself

2n/2=2/2

Answer:

n=1

Answer:

$(\frac{3}{3+5})(2 - (-14))+ (-14)$

Step-by-step explanation:

Given

Ratio = 3:5

Q = -14

S = 2

Required

Which solution uses $(\frac{m}{m+n})(x_2 - x_1)+ x_1$

From the given parameters;

$m:n = 2:5$

$m = 2\ and\ n = 5$

$x_1 = -14\ and\ x_2 = 2$

Substitute the above values in $(\frac{m}{m+n})(x_2 - x_1)+ x_1$

This gives:

$(\frac{m}{m+n})(x_2 - x_1)+ x_1$

$(\frac{3}{3+5})(2 - (-14))+ (-14)$
