Answer:
No.
Step-by-step explanation:
No because if we substitute the given values into the equation they do not fit:
y = 7x
x = 1 and y = 4:
Left side = 4
right side = 7*1 = 7.
you can't really solve for it unless it equals something or there's a value for x. Assuming this logarithm is base 10... you can set it equal to y and simplify it.
2log(x) = log(x^2)
log(x^2) = y
x^2 = 10^y
