Answer:
Value of x=8
Step-by-step explanation:
Given : 
To find : The solution to the equation given
Solution :
Step 1- Write the given expression
Step 2 - Using logarithmic laws
Step 3 - To remove log-base 2, we need to raise the left and right hand terms to power 2.
Step 4 - Solve the quadratic equation
Either x=8 or x=-2
We neglect x=-2 because negative value is not defined in log.
Value of x=8
Ok I’ll add it then I’ll answer

Answer:
y = x+7
Step-by-step explanation:
Assuming all of these numbers are ordered pairs (coordinates) when x is 1 y is 8, when x is 2 y is 9 and so on. If you notice y is going up by 1 every time so it follows that the starting point (y intercept) must be 7. Therefore, our equation will be y = x + 7.
Test it out:
Let x =2
y = 2 + 7 = 9 This matches our coordinate (2,9) so it's correct.
Let x =4
y = 4 + 7 = 11 This matches our coordinate (4,11) so it's correct.
Feel free to try out the rest of the coordinates, but usually 2 is enough to confirm that your equation is correct.
