-14 - 6x = x + 7

-3

Step-by-step explanation:

-14-6x=x+7

-14-6x+14=x+7+14

-6x=x+21

-6x-x=x+21-x

-7x=21

\frac{-7x}{-7}=\frac{21}{-7}

x=-3

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
