Question

I need help on number 29

Answer 1

When you get the same numbers on both sides of the equation. The answer is is all real numbers. Not 0

Answer 2

x = All real numbers or 0.

First you should distribute both sides of the equation. This gives you 42x+42=42x+42.

Then, subtract 42 from both sides. This gives you 42x=42x.

Now, divide 42 on both sides. This gives you x=0 or all real numbers.
