Question

What is a linear equation in x whose only solution is 5

Answer 1

x - 5 = 0

Answer 2

if you want a function, f(x) = x - 5

That solution is 0 though? Would 10 - x = 5 work?

Answer 4

yes!

Answer 5

Okay, thank you so much ^_^

10 - x = 5
10 - 5 - x = 0
5 - x = 0
x - 5 = 0, same thing
