I need help with this pls

If you're looking for the value of x, x = 4.

Step-by-step explanation:

We can immediately see that 16/4 = 4, so the equation then becomes 4x + 4 = 20. We can subtract 4 from both sides of the equation and get the new equation of 4x = 16. Dividing 4 from both sides we get x = 4.

(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.
