SOLUTION: Which of the following equations does not have all real numbers as solutions? 2(x+5)=2x+10 (x-8)/5=0.2(x-8) 4/x-5=4/x-5 x+8=13+x-5 7x= 4x+3x

Question 1045283: Which of the following equations does not have all real numbers as solutions?
2(x+5)=2x+10
(x-8)/5=0.2(x-8)
4/x-5=4/x-5
x+8=13+x-5
7x= 4x+3x

They all look like identities. What happens if you choose a value for the third equation to make it undefined? Can you find such a value?

You must have intended to show , but what happens for x=5?
