solve the equation and check -16=x+20 the solution set is?

Question

Sove the equation and check answer

 

-16=x+20

 

What is the solution set?

Answer 1

-16=x+20

If you do the same thing to both sides of the equals sign, it will stay the same. Eg if you had 2=2, then adding 5 to both sides would make it 7=7 which is still correct.

Using this method, subtracting 20 from both sides will cancel out the 20 on the right and just leave -36 on the left.

-36=x

This is the final solution.
