Answer:
the equation is equivalent, y is any number
Step-by-step explanation:
-3(3y-7) = 21-9y
-9y + 21 = 21 - 9y
-9y = -9y
y=y
any number will satisfy y=y
When we have exponents like such (x^-6)^-2 , the numbers are multiplying, so we have x^12, then we take that value and, because it is dividing with the same base, we substract the numbers, so x^12-(-4) = x^16.
