True or false. The equation 2x-7=5+x has exactly one solution.?

Question

If false, provide a counterexample. Help! Please! I don't remember how to do these problems!

Answer 1

2x - 7 = 5 + x (subtract x from both sides)

x - 7 = 5 (add 7 to both sides)

x = 12

True

Answer 2

Solve: x = 12. Yes, one solution.

2x - 7 = 5 + x; subtract x

x - 7 = 5; add 7

x = 12

Answer 3

True... I think lol  

Answer 4

True.

2x-7= 5 + x

-x           -x

x-7= 5

+7  +7

x = 12

All your really dong is the additive inverse on the variables and numbers.

Answer 5

x=12
