When solving the problem 45x−3=16x+6
, your friend does the following:
45x−3=4(x+6)
5x−3=x+6
4x=9
x=94
Was this correct?

No, in step 2, the 4 should have been distributed to the current exponents. This would change the equation and yield a different final answer.

No, in step 1 when the 16 changed to 4, it should have been 42
and the 2 distributed to the current exponent.
No, in step 1 when the 16 changed to 4, it should have been 4 squared and the 2 distributed to the current exponent.
Yes, this is correct. No error was made.

No, the bases of 4 and 16 should have both been changed to a base of 2, giving us 22
and 24
respectively.
